“IQE brings a wealth of experience in the growth of both edge emitting lasers and VCSELs for optical communications networks. “ IQE News Release Solyndra Introduces Cylindrical Panel PV System; Announces $1.2 Billion in Multi-year Orders
CompoundSemi News StaffOctober 8, 2008...Solyndra, a company based in Fremont, California USA, that produces copper indium gallium diselenide solar cells, announced a new photovoltaic system for the commercial rooftop market. The company also announced that it currently has over $1.2 billion in multi-year customer contracts in Europe and the United States
The company’s new rooftop system uses uniquely designed cylindrical modules
that capture sunlight across a 360-degree photovoltaic. The company uses the curved surface to converting direct, diffuse and reflected sunlight into electricity without the need for costly mounting on sun tracking platforms. The company says that despite mounting on tilting platforms to improve the capture of direct light, conventional solar cell arrangements on platforms offer poor collection of diffuse light and fail to collect reflected light from rooftops or other installation surfaces. Solyndra says its panels perform optimally when mounted horizontally and packed closely together. The company contends that this allows its system of tubes to cover significantly more of the available roof area and produce more electricity per rooftop on an annual basis than a conventional panel installations. Additionally the design eliminates the need for costly roof anchoring mounts and wind ballasts.
Manfred Bachler, Chief Technical Officer at Phoenix Solar AG, one of the largest solar power integrators in Europe and a Solyndra customer said, "For commercial rooftops, PV module installation time can now be measured in days, not weeks. For flat commercial rooftops this is game-changing technology." Company News Release

Sanyo Develops Blue-Violet Laser for 12x Blu-ray Write Speed
CompoundSemi News StaffOctober 8, 2008...Sanyo Electric Co., Ltd. of Japan has developed a pulsed operation 450 mW output blu-violet laser. The company says it promises 12x Blu-ray disc recording. This would be about twice the current record for Blu-ray writing of 6x, meaning that a two hour of high definition video would take ten minutes instead of 20 minutes to write. The company’s previous highest output for blue-violet lasers is 200mW with continuous operation. The company says it would be allow 100GB to be stored on a four layered disc instead of getting up to 25GB on a one layered disc using a 200mW blue-violet laser.
The company said it made three improvements to its design to create the record breaking laser. First, it improved material and reduced the amount of light absorption with its new 'LASTECT' (Low optical Absorption STructure by Endurable Coating Technology) structure that reduced the amount of light absorbed with an the end-face protective film that acts like a mirror. This virtually double its operational life to 1000 hours at 80°C. Secondly, the company increased the optical conversion efficiency through by reducing light loss from absorption in the optical waveguide's cladding layer. The company did this and boosted optical output by 10 percent by cutting the amount of impurities incorporated during layer growth in half. Thirdly, the company said that it optimized the shape of the waveguide and improved the precision of its dry etching method to ensure a more stable beam position. Company News Release JDSU Introduces New Pump Laser to Support FTTH Networks
CompoundSemi News StaffOctober 8, 2008...JDSU of Milpitas, California USA announced its new 4900 Series pump laser product. The company says it offers twice the power, improved efficiency, and a 70 percent smaller package compared to previous pump lasers for fiber-to-the-home (FTTH) networks. The pump lasers have optical power amplifiers to enable high definition TV, internet, phone, and video-on-demand FTTH services between a service provider’s central office and consumers’ homes.
According to the company, the new pump laser increases an optical amplifier’s signal power so that it can split a signal to travel over multiple fibers and reach the maximum number of homes. This lowers signal generation costs for network equipment manufacturers (NEMs) and service providers. The product reportedly doubles the laser pumps power from 4 W to 8 W, increases the efficiency by 20 percent, and is 70 percent smaller. JDSU notes that the pump laser is based on its telecom-grade L4 diode laser platform that was released in December, 2007.
“With twice the power, our customers can service twice as many homes from the same amplifier, helping them to control costs as voice, video and on demand services continue to grow in popularity among consumers,” said Toby Strite, marketing director of High Power Lasers in the Optical Communications business segment at JDSU .
