Okay, I apologize for the bad pun, but it does seem like the Fiber Optic market is finally trending upward. I attended the OFC/NFOEC Conference in Anaheim in March and although a bit late, I’m glad that April came and I can describe some of the developments. I was impressed with many of the technology, product and market developments on display.

At the top level, this market segment has floundered, directionless for the past several years. After good growth in the middle part of the 2000’s, the overall optical market ran into trouble in 2009 as the global economy faltered. The result was a drop in revenue of about 15%. With the exception of a short-lived spike in 2011, the market has been relatively flat. This behavior is understandable, because upgrading, expanding or initially deploying an optical transport network is a capital-intensive exercise and the uncertain direction of many regional economies only adds to the challenge. The wildcard in this scenario however, is the seemingly insatiable desire to consume data.

We tend to focus on growth in the mobile data consumption that is enabled by the vast array of wireless devices we’ve all grown so dependent on, but that’s not the whole story. As I am fond of pointing out, even with mobile data roughly doubling every year from 2009 to 2016, it will only account for roughly 10% of the total in 2016. The other portion of data consumption comes from Internet, high-speed broadband, CATV and enterprise data applications. Even with the backdrop of a still uncertain economy, it is becoming clear that transport network upgrades are essential to ensure future data increases are feasible.

It appears operators are finally committing the capital resources and this looks likely to set up the overall optical market for steady future growth. At the component level, another interesting trend I observed is the rapid conversion to higher capacity networks. It appears 10Gbps systems are the workhorse of the network, with lower capacity systems all but disappearing. Another thing that seemed clear was that while 40Gbps systems will grow, they won’t represent as big an opportunity as originally thought. There are currently four modulation schemes used for these networks: optical duo binary, DPSK, differential quadrature phase-shift keying (DQPSK) and dual-polarization QPSK or DP-QPSK. While this lack of standardization allows suppliers to differentiate their designs, it does not allow for economies of scale and the cost reduction standardization usually entails. At the same time, the cost of 10Gbps systems has been dropping quickly. These factors seem to be leading operators to consider jumping directly from 10Gbps to 100Gbps networks, skipping 40Gbps in the process. It appears from the Marketing presentations and the products I saw, that 100Gbps system will see the fastest growth, by far! For more information on growth rates, segmentation, quantities and market values for optical transceivers, please look at Capacity Requirements Driving Fiber Optic Market.

The other big topic at the show was silicon photonics. This idea seems to divide the audience into two distinct and passionate camps. One says, “we’ve been hearing this now for years, but where are the production products?” The other camp is more than ready to discuss the benefits of silicon CMOS processes for cost and power reduction. One thing that appears to be different from the past is the dramatic increase in enterprise applications and “big data”. As server farms grow, so does the need for fast, cheap, low power, short-reach connections. This need seems very well suited to the capabilities of silicon photonics. While the technology doesn’t appear to meet the needs of every application, there is certainly a lot of development effort and it will be interesting to see how quickly silicon photonic circuits penetrate short-reach enterprise applications. Stay tuned!

With the financial reports in the books, it’s time to close out 2012. The good news is that GaAs device revenue closed 2012 up slightly to reach another record at slightly more than $5.3 billion. The small gain was driven by strong fourth quarter performance from the industry after a sub-par third quarter just about erased the gains for the entire year.

Handsets and smartphones, in particular, remain the driving force behind GaAs device revenue growth. The growth of smartphones with their increasing GaAs device content helped propel the handset segment to more than 50% of the entire market. Not surprisingly, the companies associated with handset devices remain the revenue leaders. Skyworks Solutions again saw their revenues increase faster than the market and they remain the largest GaAs device manufacturer, stretching their lead over TriQuint. On the pure-play foundry side, WIN Semiconductors continues their impressive growth trajectory and they have become the dominant company in this segment.

We expect a good uptick in cellular terminal shipments in 2013, along with smartphones continuing to capture market share. I am expecting this will propel GaAs device revenue growth in 2013 into the 8 -10% range. With some of the predictors I use to track the market, I think there are signs that this growth is taking root. For more details, clients of the GaAs service can access my GaAs Device Industry Closes up in 2012 Insight.

However, even with above average growth looking likely in 2013, all is not rosy for the GaAs device market, long-term. The first threat to growth comes from within. The dizzying number of LTE bands, coupled with a desire for the “world-phone” has given rise to the multi-mode, multi-band (MM-MB) PA. This has some serious repercussions, because this market is so price sensitive that it will not tolerate bigger and more costly parts, so these MM-MB PAs must be smaller and cheaper than the PAs they replace or it won’t make sense to use them. We’ve already seen substantial design and design-in activity, so these devices are beginning to see commercial traction.

The other, serious threat was unveiled at the recently concluded Mobile World Congress (MWC). Qualcomm fired the first shot across the bow with their pre-conference announcement of the “RF360”. The company calls this family of devices a complete, all-encompassing CMOS RF front-end subsystem. This subsystem consists of an antenna tuning IC, an envelope tracking (ET) IC for Qualcomm’s PA and a MM-MB CMOS PA fabricated using a silicon-on-insulator (SoI) substrate. This announcement sent stocks of the GaAs PA manufacturers plummeting to levels from which they are still trying to recover. Then at MWC, a whole host of companies announced their ET development efforts aimed at CMOS-based PAs in LTE handset applications. A detailed summary of these announcements and developments is contained in PA Market in Flux: CMOS PAs and Envelope Tracking Emerge as Major Themes at MWC 2013 from Strategy Analytics’ RFWC service.  

These events and particularly the development on the CMOS front will certainly influence the growth trajectory for GaAs devices in the next several years and merit close attention. If you plan to attend IMS2013 in Seattle, stop by the panel session I will be hosting entitled “The Death of GaAs (?)” on Thursday, June 6^th at 12:00PM. We’ve have some market overviews, short presentations from a number of GaAs and silicon-based device manufacturers and then a lively discussion. If you can’t make the IMS2013 conference, you can also catch up with me at CS MANTECH in New Orleans on May 13 – May 16. I’ll be presenting an overview of the 2012 GaAs market and I’d be happy to chat.

I didn’t want to let this news item slip away without comment because it has some serious implications for the GaAs epitaxial wafer market. On January 10 2013, IQE announced they agreed to acquire the compound semiconductor epiwafer manufacturing business of Kopin Corporation for total consideration of $75 million in cash. This follows up on the announcement earlier in the 2012 that IQE had signed what they describe as a “multi-faceted agreement” to acquire the entire in-house MBE epiwafer manufacturing unit of RFMD. In exchange for the transfer of these assets, there will be no upfront cash outlay. Instead, the two companies have agreed to a seven-year wafer supply agreement, with a minimum purchase commitment of $55 million over the first two years. This agreement will result in IQE being the exclusive supplier of all of RFMD’s MBE wafer requirements and a majority of its MOCVD wafer requirements under a discounted pricing arrangement.

In our last Forecast and Outlook Report: Markets for Semi-Insulating GaAs Epitaxial Substrates: 2011 - 2016, I concluded that IQE was the dominant merchant vendor of MBE epitaxial substrates with almost 85% of the market and the largest overall merchant supplier by virtue of their ability to supply both MBE and MOCVD substrates. My analysis ranked RFMD as the fourth largest and Kopin as the third largest overall suppliers of epitaxial substrates. With the acquisitions, IQE is poised to be the dominant epitaxial wafer manufacturer with more than 50% of the entire market. Their dominance in the MBE market is enhanced by RFMD’s capability and the Kopin acquisition roughly triples their MOCVD capability. This allows IQE to vault from a distant third in this segment past VPEC into first place. The enhanced MOCVD capability enables them to get a firm foothold in the growing handset PA market through the wafer supply agreement with RFMD and the customer relationship Kopin had with Skyworks.

It appears clear that IQE will have a stranglehold on the epiwafer segment. Based on 2011 results, they will be almost three times as large as VPEC, their closest competitor. The deals make perfect sense for IQE; they extend their dominance in the MBE segment and gain a much-needed boost in the MOCVD segment, along with relationships to RFMD and Skyworks. From the RFMD perspective, most if not all of their handset switches have transitioned to SoI as the technology of choice, making it difficult to keep the 16 operational MBE tools they are transferring to IQE busy. While Kopin has been a very strong competitor in the III-V epitaxial wafer market segment, they have obviously chosen to cast their lot with the display technology they have been developing and with that focus, the epiwafer portion of their business no longer fit the company’s direction.

These announcements, coupled with an earlier announcement of an exclusive supply contract and strategic investment in CPV module manufacturer, Solar Junction Corporation was a very loud statement of IQE’s intention to consolidate the epiwafer space and diversify end markets. The challenge in acquisitions is always the successful integration of the new parts, but barring any missteps in that area, IQE looks poised to be the dominant epitaxial wafer supplier. It will be interesting to see how these acquisitions change the epitaxial wafer landscape, so stay tuned for more insights and forecasts in the upcoming months.

While I try to get current with product and financial announcements, I thought I’d spend a moment discussing some of the news from the July to September quarter. The two recently published reports: “Compound Semiconductor Industry Review July - September 2012: Microelectronics” and “Compound Semiconductor Industry Review July - September 2012: Optoelectronics, Materials & Equipment” highlight financial, product, contract and employment announcements from the compound semiconductor industry. The executive summaries of both reports focuses on the financial aspects of the industry and both segments are facing some challenges. The microelectronics segment appears to be trending upward, but it is still challenged to reach the revenue levels the industry saw in 2011. With the close of 2012, I see no reason to change my stance that when the revenue is counted, we will see a slight growth, but growth nonetheless.

On the optical side of the house, the picture is much fuzzier. The LED industry is still reeling from subsidies that have slowed and is plagued by a dramatic decrease in price, even in the face of slow unit growth. This is not only affecting the LED industry, but the material and equipment portion. Solar power continues to see a lot of political momentum as the best thing for the environment, but companies are still struggling to make money. The report has almost as many companies reorganizing and shutting down operations as those that are increasing capability, so the best direction for the industry is still not clear.

While the financial aspect is very important, it has masked some very interesting product development trends in both segments of the industry. It should come as no surprise that GaAs is under fire from other compound semiconductor technologies like GaN and SiGe, but also increasingly from silicon CMOS-based processes. The breadth of companies developing these applications is growing. On the microelectronics side, the report captures an announcement from Amalfi Semiconductor that they shipped their 100 millionth CMOS PA. Javelin also announced a CMOS PA design win in a Samsung 3G phone. The success of the CMOS PA manufacturers has been pretty evident. In the past year or so, Axiom Microdevices (Skyworks) and now Amalfi (RFMD) have been acquired by larger “GaAs manufacturers” as these companies make a relatively small defensive bet on CMOS technology as a hedge against their stakes in the nearly $3 billion handset PA market.

However, the CMOS target is not just handset PAs. The reports also capture RFaxis announcing seven new products aimed at high-volume markets as part of their “turn off the GaAs” campaign. Fujitsu announced a CMOS-based power detector and Silicon Labs and Avago announced a CMOS optocoupler. Even companies closely associated with GaAs are expanding their silicon offerings with Skyworks announcing a driver for LEDs and Hittite expanding their silicon-based ADC and clock generator offering.

So, the battle is on. The reality is that there is no perfect technology and the market selects the best solution. I’ve been saying that while silicon has a number of advantages, don’t count GaAs out just yet, especially where performance targets are steadily increasing. In a shameless plug, if you plan to attend IMS2013 in Seattle, stop by for a panel session entitled “The Death of GaAs (?)” that I will be chairing. I’m sure we will have a lively session discussing many of the same issues that I’ve raised here!

As we get set to close the book on 2012, I thought I’d share some observations about the trends and results for the compound semiconductor industry. First and foremost, it hasn’t been a banner year, but the GaAs device market looks like it will eke out a small gain. Through three quarters, revenue in the device industry is showing a very small gain. On a positive note, many of the large GaAs device manufacturers have stated they are optimistic about their calendar fourth quarter prospects. This makes me optimistic the GaAs device industry will come close to the 2% growth I forecast at the beginning of the year. In addition, the GaAs revenue “pressure curve” (a concept I introduced in the “At the Halfway Point of 2012: GaAs Device Industry Shows Small Gain “ blog) has shown an upward trend with a value greater than 1 the past two quarters. Essentially, the pressure curve is a rolling average, so a value greater than 1 indicates growth and with companies optimistic about Q4, it wouldn’t be surprising to see another upward tick in the indicator.

This indicator fits well with our latest forecasts. The inescapable conclusion is growth in the handset market is still the single largest driver for the overall GaAs device market. This “growth” isn’t just unit growth, it also relies heavily on smartphone penetration since these devices contain more GaAs content than lower tier devices. After a flat year in 2012, our latest forecasts show much healthier growth in handsets and power amplifiers in 2013. The unit growth will be important because as smartphones become more prevalent, the rate of growth is slowing. Return to healthy growth for handset PAs, which make up more than 50% of the overall GaAs device market, bodes well for growth in 2013.

Most of the growth in the GaAs device market in the last 18 months can be attributed to handsets, as the network side of the market has been flat. While a tentative global economy probably is not helping, the time for increasing network investment would seem to be nearing. Data consumption continues to increase dramatically and this is placing a burden on all the networks, whether they are wireless or wired. In the upcoming year, I plan to update research on the wired CATV/broadband and fiber transport networks, along with developments in the wireless backhaul, infrastructure and VSAT networks to get a better understanding of the trends and drivers in these areas, so stay tuned for those updates.

As a final thought, I’d be remiss if I didn’t mention GaN. This technology continues to attract a significant amount of interest in the compound semiconductor industry. It finally appears that we are getting commercial adoption of GaN-based devices and we can see the point of inflection for volume. CATV amplifiers continue to lead this commercial adoption, but we are hearing about more activity for GaN in wireless infrastructure, VSAT, high power electronics and even point-to-point radio applications. The tricky part is determining exactly where we are in relation to the point of inflection. I’m not completely sold on the hype (again), just yet, but I am willing to concede there is much more activity than a year ago. This is another topic that I will be diving into early in 2013 to get a better sense of the market.

As I sharpen my pencil for 2013, I’d like to wish everyone a very safe and happy holiday season and a prosperous New Year!

I hope everyone had a chance to attend the GaAs Market Trends & Results webinar I hosted last week. If not and you are interested, please click on the link to view the replay. The RF GaAs supply chain remains very dynamic, with some interesting trends driving the substrate and device portions of the market.

As I’ve mentioned in previous blogs and presentations, the top-level driver for GaAs devices continues to be the increase in data consumption. Some of the latest estimates have mobile data consumption growing at rates approaching 100%, which means IP data consumption will double every year from 2009 – 2016! Even with this impressive growth, these estimates claim mobile data will still be less than 10% of total IP data in 2016. This is important, because while wireless applications continue to drive the GaAs industry, the wired broadband, CATV and transport networks and enterprise applications are also growing and represent opportunities for GaAs devices.

One of the advantages of GaAs is the performance makes the technology useful for a wide variety of commercial and defense applications. So, while the entire industry must continually pay homage to the handset portion, the diversity of applications does help buffer some of the market instabilities. The result for 2011 was another year of revenue growth in the GaAs market. This roughly 6% growth raised GaAs device revenues to about $5.2 billion. Neglecting an essentially flat year in 2009, GaAs device revenues have grown since a decline in 2004, so things have been good in the GaAs supply chain.

There are some storm clouds on the horizon, however. Handset opportunities represent more than 50% of all GaAs device revenue and the broader handset market does not grow explosively. The GaAs market has been helped by the shift toward feature phones and smartphones that have much higher GaAs content and the introduction of more and different frequency bands of operation. Many of the large handset device OEMs have converted from GaAs to SoI for handset switches, turning the handset GaAs opportunity increasingly into a power amplifier opportunity. Since handset switches are very inexpensive, this conversion has not had much effect on GaAs revenue, but the quantity reduction has had a definite impact on the bulk and epitaxial wafer manufacturers. We’ve seen reductions in demand and an upswing in MOCVD production at the expense of MBE devices.

In addition, we’ve all gotten used to larger smartphones that accommodate bigger screens, but you’ve probably noticed a trend toward thinner phones. To meet the demands of more frequencies and form factors, the device OEMs are releasing multi-mode, multi-band amplifiers that allow a single device to replace multiple existing PAs. Given the price and volume pressures from the handset market, it is unlikely that the multi-mode amplifiers will be larger or more expensive than the amplifiers they will replace, so this looms as a potential issue for the substrate and device markets.

However, even with the storm clouds, the GaAs device market has proven to be very resilient. As long as the performance requirements for the various applications keep increasing, GaAs has historically proven to be up to the challenge. Even with smartphone growth slowing (still strong, but slowing), the avalanche of data consumption is driving things like new Wi-Fi standards, higher frequencies for wireless backhaul, “small cells” in wireless infrastructure and higher data rates in transport networks. All these developments should give a boost to the GaAs supply chain.

Since we are almost through 2012, I should add a thought or two about where the market appears to be headed. It looks like we will see some growth in 2012, but at a much lower rate than the historical average of 6%. On a positive note, in a previous blog (At the Halfway Point of 2012: GaAs Device Industry Shows Small Gain ), I introduced the idea of “pressure curves”. While the results are not complete yet for calendar Q3, initial indications show the GaAs market is growing. This, coupled with positive guidance from some of the larger GaAs device OEMs for calendar Q4, may mean we are in for a bit of a rebound, so stay tuned.

I attended the recently concluded SCTE Cable-Tec Expo and came away impressed with the amount of system and component development activity in this industry. What started as a solution for homes that could not get adequate over-the-air broadcast TV signals, has become intertwined with cable-based broadband data services as service providers look to capture an increasing share of the “triple-play” of voice, video and data. The lines of distinction among the service providers is also getting blurry as traditional voice operators like AT&T and Verizon in the US offer broadband and TV services and cable operators like Comcast and Time Warner Cable offer broadband and VoIP voice services, in addition to the traditional TV offerings

The convergence of triple-play services also brings the challenge of designing networks that are scalable enough to deal with the explosion of data consumption. Several of the presentations referenced “the Nielsen Curve” that plots the maximum downstream data rate over time. This curve shows a very steady 50% yearly increase from the 300 bps performance in 1982 to 12Mbps in 2007. A couple authors were arguing that we are now in an era of “wideband” cable modems and the data rates have actually been increasing faster than 50% for the past few years!

There are several ideas about the proper architecture (or mix of architectures) required to handle this 50% (or higher) increase in downstream data rates that is being fueled by video, higher internet data speeds and more TV channels. The other aspect of the architecture challenge is what to do about the return or upstream signal. As user experience becomes more interactive, the data requirements increase on the upstream path, as well.

The new architecture ideas include running fiber as deep into the network as possible. While this solves the bandwidth problem, several of the large MSOs pushing this approach are having a hard time making the business model work, despite healthy numbers of subscriber additions. Networks that use EPoC (Ethernet PON over Coax) and DPoE (DOCSIS Provisioning of EPON) offer transport advantage over more traditional HFC networks without the cost of “fiber deep”. The industry is discussing changing the traditional 5-42 MHz return path bandwidth and in what portion of the spectrum to locate this additional bandwidth. In conjunction with this discussion invariably comes the discussion to extend the band to 1.2 GHz, from thecurrent1GHz (or below) physical plant. Finally RFoG (RF over Glass), where RF signals are transported over fiber (allowing the MSOs to maintain much of their HFC headend and back office equipment is still being touted as a viable option. Also in the mix are network concepts like SDV (switched digital video), node-splitting and hybrid gateways.

So, there are many options available to get to a stated goal of 2.5Gbps downstream and 1Gbps upstream cable data rates. There were a couple of presentations that did modeling to show that with the proper mix of existing technologies (node-splitting, SDV, hybrid gateways and the appropriate phase-out of analog channels), operators can accommodate the expected high-speed data, video-on-demand, HD and IP video) for the next decade with a 1 GHz physical plant! The dilemma for operators and equipment manufacturers is to determine the appropriate mix to satisfy their particular mix of SD, HD and analog TV channels, as well as accommodating broadband data rates and planning for DOCSIS3.1 and the eventual move to an all-IP network: a difficult choice indeed!

However, other than making for a dynamic environment in an industry known mostly for stability, why do we care? How the architecture discussion plays out will have major implications for compound semiconductor opportunities in this market segment. As fiber goes deeper into the network, whether this is directly through fiber to the premises deployments or increasing use of PON architect, fewer RF components may be required. Advances in GaN technology by companies like ANADIGICS, RFMD and TriQuint may also limit the compound semiconductor opportunity in this market. In addition, how does the industry answer the frequency split/extension question? Many of the return path products are designed to meet the 5-200 MHz option being discussed and the downstream path components routinely have bandwidth above 1 GHz different solution will create more development work.

Stay tuned for more in-depth analysis of this market and I do look forward to the days of 2.5Gbps downstream data rates!

I just posted theGaAs Five Year Forecast: 2011- 2016on the website and I am happy to report that the GaAs device industry continues to be very resilient. Despite an uncertain direction in the global economy, our research shows the GaAs device market closed 2011 with nearly 6% growth and record revenues of slightly more than $5.2 billion. In fact, our analysis shows the GaAs device market has not declined since 2004 when it stood a shade below $2.4 billion. I’m taking a bit of artistic license with that statement, because we have reported that the market in 2009 “declined” by less than 0.5%, but given the economic meltdown in the US at the time and the nature of the forecasting business: I’ll put that year on the good side of the ledger.

So why is the GaAs market so resilient and less sensitive to economic cycles than other semiconductor technologies (and I’m talking about you silicon)? I think the answer lies in the performance dimension of GaAs technology. We’ve all probably heard the saying “if silicon can do something, it will”. I believe that statement and we’ve certainly seen examples where if silicon-based technologies catch up to the performance of GaAs, the cost advantages make it an easy decision to eliminate GaAs. Keep in mind, among the first applications for GaAs technology were “high-speed” digital logic and where has that market gone? We are seeing SiGe devices in LNA applications and high-frequency transceivers and we are even starting to see CMOS used for handset PAs. The common thread in the application where GaAs is being displaced is a relatively stagnant technology environment. This may be the result of long design cycles, slow upgrade of standards, specifications that remain “good enough” for a long time or a number of other reasons. Where GaAs has proven resilient and risen to the challenge is where the requirements are moving “up and to the right” quickly. As handsets have become more sophisticated with the number of frequency bands increasing quickly, GaAs is still the most capable technology. As Wi-Fi standards evolve to incorporate millimeter wave frequency and multi-gigabit speeds, the displacement of GaAs in this segment does not look quite so certain.

So, why have I gone off on a bit of a tangent? It’s because we are in a period where GaAs will have to show its resiliency once again. We may be looking at a prolonged period of global economic uncertainty that will not help the business models for network capex or consumer spending. For the last couple of years, tremendous growth in smartphone sales have really helped pull the GaAs market along, but saturation is somewhere ahead and growth rates are slowing. In addition, GaAs is still seeing stiff and growing competition from GaN, SiGe, LDMOS and CMOS.

I remain optimistic that the GaAs device market will continue to grow and the report details the effect the trends I’ve mentioned will have on the GaAs bulk and epitaxial substrate market at the very front-end of the GaAs supply chain. The underlying drivers for GaAs growth; data consumption, more GaAs content in handsets, the need for higher capacity wired and wireless networks are still in place. However, I think that the economy is the wildcard. If it doesn’t improve, the growth we see in the next few years may be below historical averages. Now, I’m not a betting man, but despite the apparent gloom, I’m not so sure anyone should bet against the GaAs industry, given the track record of resiliency!
