Located in the UC Berkeley college of Engineering, the group is headed by Prof. Eli Yablonovitch, CV, a pioneer in the field of optoelectronics and photonic band-gap research. Our laboratory is comprised of many talented and dedicated graduate and post-doctoral researchers. Our work is focused on the exciting, innovative fields of optoelectronics, high speed optical communications, high efficiency light-emitting diodes and nano-cavity lasers, and photonic crystals at optical and microwave frequencies.

Prof. Yablonovitch is the Director of the NSF Center for Energy Efficient Electronics Science
