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 6th 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.

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!

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!

I recently posted the results and forecasts for the GaAs epitaxial substrate market. The Excel data model is entitled "GaAs Epitaxial Substrates 2011-2016" and the accompanying Forecast and Outlook report is "Markets for Semi-Insulating GaAs Epitaxial Substrates: 2011 - 2016". Our survey results indicate GaAs epitaxial production saw a small (between 2-3%) gain in 2011. This small gain was the result of opposite trends in the two major epitaxial processing techniques, however. As I have been reporting, the demand for pHEMT devices dropped significantly, decreasing by nearly 7% in 2011. The primary reason for this appears to be several large GaAs device manufacturers converting from GaAs to silicon-on-insulator for handset switches. An increase of about 9% in MOCVD processed wafer demand was able to offset the decline in MBE wafer epi and the overall market rose slightly. MOCVD wafers are closely associated with HBT devices used for handset PAs and this underscores the important role these types of devices play in the overall GaAs device market.

Despite the small increase in epitaxial wafer demand, the market revenue grew by almost 20% to nudge jsut past $600 million. The supply chain disruption that spiked pricing in the GaAs bulk substrate market also seemed to have had the same effect on the epitaxial wafers. This price increase is likely a one-time event and epi wafer pricing will return to a more typical price reduction curve starting this year. This, coupled with the slow growth period the entire GaAs market will be in for the next several years will lead to a declining market value through 2016.

The good news is there will be slow growth in device, epi and substrate demand, fueled primarily by handset growth in general and the continued penetration of smartphones. Driven by handset growth, it is not surprising that we believe MOCVD wafer production will increase through the forecast period. What may be surprising is I expect MBE wafer demand to also increase, albeit at a much slower rate than the MOCVD production. I think most of the transition from GaAs to silicon-on-insulator has already taken place and it is unlikely that excess MBE process capacity will remain idle. I think it is far more likely that this MBE and pHEMT capacity will be re-tasked to other high performance markets and this will create the opportunity for some growth.

The Strategy Analytics GaAs and Compound Semiconductor Technologies Service (GaAs) viewpoint, “Compound Semiconductor Industry Review October-December 2011: Optoelectronics, Materials and Equipment,” captures product, technology, contract and financial announcements from major material, device and equipment suppliers in the optoelectronics market supply chain, such as AIXTRON, IQE, Kopin, Oclaro, GigOptix, Cree, JDSU, Avago Technologies, Finisar and Osram. These announcements are categorized by material and equipment, laser, LED and compound photovoltaic activity.

Despite recent, highly publicized problems at Evergreen Solar and Solyndra, solar energy continues to play an essential role in political strategy as government and the private sector seeks viable sources for renewable energy. It is easy to get a negative outlook about an entire segment when a couple of the high profile participants run into difficulties. The reality, however, is that solar energy has become a widely deployed form of alternative energy. The product development announcements we captured in Q4 provide a counterpoint to the bankruptcy proceedings at Evergreen Solar and Solyndra and show growth and activity in the compound photovoltaic technologies which underpin the solar market.

The growth starts at the begiining of the supply chain with commitments of $2 billion to increase polysilicon production by 23,000 metric tons per year. Companies like Spire, Avancis, Soitec and First Solar are expanding their photovoltaic module manufacturing plans and TSMC, through its TSMC Solar subsidiary has entered the module manufacturing arena. These announcements, coupled with more companies reporting efficiency records for solar cells points to a vibrant industry with good opportunities for compund semiconductor materials.

The outlook in the LED sector is not quite so upbeat. AIXTRON, one of the leading semiconductor equipment manufacturers reported a steep drop in revenue and orders in 2011. They blame high levels of government funding in China and financing pressures on the Asian LED manufacturers for masking a significant organic slow down in LED demand in China. It appears production in 2012 will continue to grow, but perhaps not enough to offset price erosion. Despite, this, there is still a signficant amount of development activity at companies like Cree, Bridgelux, Epistar and Luminus. These developments aim at increasing efficiency, output and affordability for applications ranging from low power consumer devices to high intensity specialty lighting and streetlights.

The latest GaAs Optoelectrponics Industry Viewpoint, entitled "Compound Semiconductor Industry Review July-September 2011: Optoelectronics,” summarizes financial, product, contract and employment announcements from major optoelectronic material, device and equipment suppliers. These announcements are categorized as material and equipment, laser, LED and compound photovoltaic activity. During this quarter, the financial results for companies in the overall optolectronics segment were generally positive, with the majority of companies reporting quarterly revenue increases. There was a potential storm cloud on the horizon as leading equipment manufacturer Aixtron lowered revenue expectations for the year (2011) by 25%. When a leading equipment manufacturer in the very front end of the supply chain revises revenue and backlog expectations substantially downward, the entire segment takes notice. While mid- to long-term prospects for the LED market remain positive, continuing economic turmoil and rapidly dropping prices have manufacturers in the LED supply chain on edge.

Development activities across the entire sector continue to be strong. In the LED segment, blue LEDs appear to be in high demand. AIXTRON announced orders (despite the revenue warning) from several companies for equipment to be used in the manufacture of blue LEDs and Avago, Osram, Cree, Bridgelux and EpiLEDs all made product announcements of new blue LEDs. In the optical transport market, component developments targeted 10Gbps and above, while system developments also targeted data rates of 32Gbps and above. In this area,  Neophotonics announced 10Gbps transceiver modules for GPON applications and a 40Gbps transceiver for 10km single fiber applications. GigOptix, Finisar, Oclaro and Mitsubishi Electric all demonstrated 40Gbps modules, with Oclaro announcing a 100Gbps receiver.

The photovoltaic segment also saw a lot of development activity with the US government continuing to jump-start alternative energy initiatives. The US DoE announced $4.5 billion of conditional loan guarantees to support three alternating-current CdTe thin-film PV generation facilities that will total more than 1.3GW of capability. They also announced round 8 of funding opportunities for solid-state lighting technology and a $197 million loan guarantee for facilities that will produce about 400MW of flexible CIGS modules each year. The approach seems to be working, as several activities previously linked to DoE loans made announcements in this quarter. These plants target more than 560MW of solar energy output.

As Seoul Semiconductor targets the US market with a 100 lm/W LED (which effectively incorporates a rectifier within the device) aimed at general lighting applications, and Cree reports breaking the 200 lm/W barrier with a laboratory demonstration, demand for highly efficient GaN-based emitters is at an all-time high. A major reason for that is rooted in Seoul’s own backyard: Samsung is largely responsible for a recent ramp of chip production required to service its own LED-backlit TVs, while Seoul is a key supplier to LG Display for the same application. The major LED consumers are finding ways to cut down the number of chips needed in key applications (for example, the 2.6mm-thick 42-inch TV that LG Display showed off at January’s Consumer Electronics Show required only 264 LEDs in its ultra-thin backlight), but it is clear that the rapid success of LED backlights in TVs, coupled with rising interest in general lighting applications, is placing the LED supply chain under some strain. Orders for the MOCVD equipment required to make LED epiwafers are through the roof, and the industry appears to have entered a sustained period of capacity-constrained supply, potentially limiting overall LED market growth. Responding to the ramping needs of LED makers, Veeco has just launched a new, higher-yielding version of its K465 tool, while Aixtron is investing up to $40M in a research facility to develop next-generation deposition equipment. The current strong cycle of demand for LEDs looks like a precursor for a much larger one in the future that will be focused on general lighting. Seoul begins mass production of its 100 lm/W LEDs  in the current quarter, but by the time the lighting market really takes off for the likes of Osram, Cree and the rest, the LED industry’s supply chain may look a little different. While the leading merchant MOCVD tool suppliers Aixtron and Veeco are scaling up efforts to service that demand, the unprecedented market pull for LEDs appears set to bring additional competition. That comes in the form of another Korean firm: Jusung Engineering. In mid-January, Jusung installed a “beta” MOCVD tool at Epivalley, also in Korea, and clearly senses an opportunity to muscle in on Aixtron and Veeco territory with its high-capacity (124x2-inch) tool. Applied Materials appears to have similar plans and we may see the market landscape for tool suppliers change significantly over the next few years.
