only recognises Professor DenBaars’s pioneering research in the area of solid state lighting and displays, but also his commitment to applying this research in order to improve the lives of people around the world,” said Chancellor Henry T. Yang.
“Election by one’s peers to the National Academy of Engineering is a very important and meaningful affirmation of years of innovation, creativity, and hard work. Our entire campus community proudly congratulates Professor DenBaars on his outstanding achievement.”
DenBaars, who joined the UCSB faculty in 1991 as an assistant professor of materials, is the Mitsubishi Chemical Professor in Solid State Lighting and Displays. He is also co-director of the campus’s Solid-State Lighting and Energy Centre. The author or co-author of more than 600 technical publications, his specific research interests include the growth of wide-bandgap GaN- based semiconductors, and their applications to Blue LED’s and lasers, and high-power electronic devices. UCSB says this research led to the first U.S. university demonstration of a Blue GaN laser diode.
DenBaars received a National Science Foundation Young Investigator Award in 1994, and the IEEE Fellow award in 2005. He has made over 250 invited conference presentations and has been awarded over 30 patents. His election brings to 25 the number of current UCSB faculty members in the National Academy of Engineering.
Before joining the faculty at UCSB, DenBaars was a member of the technical staff at Hewlett-Packard’s Optoelectronics Division, involved in the growth and fabrication of visible LED’s. He is currently a scientific advisor for Cree Lighting. Among his many honours and awards are the 2010 Aron Kressel Award from the IEEE Photonics Society, the 2008 Japanese Science of Applied Physics Outstanding Paper Award, and the 2007 Viterbi Award and Distinguished Alumni Award from the University of Southern California.
Kaistar lights up Bridgelux with $25 million investment
The LED developer will use the cash to accelerate research, development, and production of LED chip and packaging technology for general illumination applications
“The market for solid-state lighting is expected to grow from $3 billion in 2011 to more than $25 billion in 2015,” said Bill Watkins, Bridgelux’s Chief Executive Officer. “This investment marks the beginning of our cooperation with Kaistar to lead the transition to solid-state lighting. Kaistar’s cost- competitive manufacturing capabilities combined with Bridgelux’s high performance packaging solutions will continue to drive down the cost of solid-state technology for general lighting, helping to more rapidly expand the market for LED.”
Kaistar Lighting (Xiamen) Co., Ltd. is a China-based firm.
