SOMERSET, N.J. -- Emcore Corp. here announced this week that the University of California at Santa Barbara has ordered an Emcore SpectraBlue gallium nitride (GaN) production platform for development of GaN-based laser diodes and electronic materials and devices.
The research work is being performed by professors Shuji Nakamura and Steven DenBaars. Nakamura joined the faculty of UC Santa Barbara last month from Nichia Chemical K.K. in Japan. He has made substantial contributions in the field of blue lasers and blue spectrum high-brightness light-emitting diodes (HB-LEDs) based on GaN epitaxy, Emcore said.
The university and the company have established a formal research collaboration providing for feedback from UCSB about tool performance to Emcore that will enable Emcore to make design and performance improvements in its metal oxide chemical vapor deposition (MOCVD) tools.
"Emcore's SpectraBlue tool is rapidly becoming the industry standard for GaN production. With this tool UCSB will be better equipped to continue its strong tradition of leading research in materials science," said Nakamura. "Our new Emcore platform will be used for the development of even more efficient GaN-based optoelectronic and electronic materials."
Nakamura and DenBaars have ordered a standard SpectraBlue production tool, of which more than 70 are currently in operation throughout the world, according to Emcore. Emcore's E2M division currently is using the SpectraBlue to provide the GaN epitaxial material capability in support of GELcore, its joint venture effort with GE Lighting. GELcore develops HB-LED-based lighting systems for GE Lighting.
HB-LEDs are moving rapidly into the commercial marketplace, in energy-efficient lighting for full color large screen and flat panel displays, for traffic and warning signal, automotive brake lights and interior lighting, and new sources of energy-efficient white lamps.
Blue, green and violet lasers, based on GaN epitaxy, hold the promise of a significant increase in next-generation DVD and optical disk drive capacity. Blue lasers are expected to revolutionize the optical storage industry, potentially increasing information storage capacity four-fold.
Strategies Unlimited, a market research firm, forecasts that the market for blue DVD lasers will overtake and eventually surpass current red laser technology by a factor of four in 2006.
"Emcore is extremely pleased that Professors Nakamura and DenBaars have elected to base their next-generation GaN work on our SpectraBlue production platform," said Reuben Richards, president and CEO of Emcore. "We have justifiably high expectations for our tool in the hands of these famed professors, and look forward to a long, productive partnership between them and Emcore. Their contributions to the continuous improvement of our GaN reactors are expected to further optimize the performance and processes of our popular SpectraBlue platforms."
