Biography

Steven DenBaars is a Professor of Materials and Electrical Engineering at the University of California SantaBarbara. From 1988-1991 Prof. DenBaars was a member of the technical staff at Hewlett-Packard's involved in the fabrication of High Brightness LEDs. In 1991 he joined the faculty of the University of California where he is developing new solid state optoelectronic devices. He research also involves MOCVD growth of GaN and InP based tunable lasers and detectors. He has received a NSF young scientist award (1995) and the Young Scientist Award from the International Symposium on Compound Semiconductors in 1998. Currently, he is an associate director of the solid state lighting and display center (SSLDC) at UCSB, which is developing new more energy efficient light sources. Special interests include the effect of materials properties on device performance blue VCSEL lasers and microwave power transistors. He has Authored over 200 technical publications, 3 book chapters, 100-conference presentation, and over 7 patents.
