Profitability of the Optical Component Business Improved Last Year and It May Set a New Record in 2016

The average profitability of optical passive component and module suppliers was very close to zero over the last 5 years, despite strong demand for optics. Compared to every other level of the industry supply chain, profitability of the optical component manufacturers was the lowest by far.
Financial reports of several suppliers of optics started to show signs of improvement over the last 2-3 quarters. The average profitability of optical component and module vendors was 2% in 2015, compared to a loss of 1% in 2014. There is a good chance for reaching 5-7% profitability in 2016-2017 and setting a new record. The highest profitability achieved so far was 5.5% in 2010, preceded by more than ten years of heavy losses.

Several component vendors restructured their businesses in 2013-2014 and these efforts are starting to pay off now. Accelink, Applied Optoelectronics, Coadna, Neophotonics and Oclaro reported significant improvements in financial performance. Acacia joined the list of publicly traded vendors recently and holds the record with a 17% net margin for 2015. Finisar’s profits started to improve in the second half of 2015 and we expect this trend to continue.
However, the average profitability is likely to stay in the single digits for a while. This industry is very competitive and it is likely to remain so for the next several years. Demanding customers, shorter product lifecycles and investments required to support development of new products are a heavy burden for suppliers. There are close to 40 vendors in the race to offer 100GbE optics to the cloud companies building mega-datacenters. Not many of these vendors will be successful in the long term, but they will continue to put pressure on the profitability of larger publicly traded companies in the industry.
Many start-up companies, betting their future on supplying high-speed optics to cloud vendors, develop products based on silicon photonics and expect that this new technology will give them a sustainable cost advantage. LightCounting’s report on Integrated Optical Devices offers detailed analysis of the opportunities for silicon photonics technology, and recognizes the potential advantages of this technology. However, we expect that a majority of high-speed Ethernet optics used in mega-datacenters will still be based on more established InP and GaAs based optics even in 2021.
Despite all the risks, developing new manufacturing technologies offers a path to sustainable competitive advantage and long-term profitability. Silicon photonics holds a promise for being such a technology. High-valued acquisitions of silicon photonics companies and the recent IPO of Acacia offered much needed success stories for investors. However, the risk remains high. Many other vendors, starting just to ship silicon photonics based products now, will have to prove themselves in 2016-2018.

DK Photonics now can write Fiber Bragg Gratings for fiber lasers on demand

Fiber Bragg Gratings for fiber laser
Laser Mirror Gratings
China, 21th July, 2016Optical passive components available at DK Photonics are significant in a number of industries such as telecommunication applications, fiber laser, etc. In order to better give our fiber laser customers to do matching service, DK Photonics work with a Chinese optical research institute, after more than half a year's efforts, and finally produced the FBG Mirrors used for fiber laser.
FBG Mirrors are based on the reflective properties of the Fiber Bragg Grating (FBG) written in the core of an optical fiber waveguide. FBG mirrors’ principal application is to use a high and low reflector to form a stable laser cavity having the lasing wavelength selected by the low reflector.
Fiber Bragg grating (FBG) is a distributed reflector constructed in an optical fiber short segment that allows reflecting particular wavelengths and transmitting the rest of them. The periodic variation of the fiber core refractive index generates a wavelength-specific dielectric mirror, which allows reflecting specific wavelengths. FBG can be used as a high reflector (HR) and output coupler (OC) to make a laser cavity in a fiber laser. Rare earth doped optical fiber increases the laser gain. The major advantage of all-fiber systems where free space mirrors are replaced with a pair of fiber Bragg gratings (FBG’s) is that the realignment process is no longer needed for the entire system functioning period, since FBG is spliced directly to the doped finer and never needs adjusting.
DK Photonics can provide varied wavelengths FBG, such as 1018nm, 1053nm, 1064nm, 1080nm, 1550nm, 1950nm, 2020nm, 2040nm; and can write in all common passive optical fibers, such as 6/125DCF,10/125DCF,15/130DCF,20/125DCF,25/250DCF,30/250DCF,20/400DC Fiber, PM or non-PM types are available.

Applications
FBGs offer multiple applications. It can replace conventional dielectric mirrors to provide optical feedback. It can be also used to create a multi-wavelength Raman fiber laser.
Fiber lasers offer a compact, electrically efficient alternative to Ar-Kr and Nd:YAG technologies. The FBG can be applied to fiber lasers of any type:
  • Single frequency fiber lasers;
  • Raman fiber laser;
  • Fixed frequency visible wavelength lasers;
  • Tunable frequency visible wavelength lasers;
  • Ytterbium doped fiber lasers;
  • Q-switched fiber lasers;
  • Pulsed fiber lasers;
  • Stabilized multi-mode emission sources;
  • Fine optical fiber responder, etc.
