Research Groups


Larry A. Coldren is the Fred Kavli Professor of Optoelectronics and Sensors and holds appointments in Materials and Electrical & Computer Engineering. In addition, Coldren is a leading researcher with the Institute for Energy Efficiency’s Electronics and Photonics Solution Group. Coldren received his Ph.D. degree in Electrical Engineering from Stanford University in 1972. After 13 years in the research area at Bell Laboratories, he joined UC Santa Barbara in 1984 and is Director of the Optoelectronics Technology Center. In 1990 he co-founded Optical Concepts, later acquired as Gore Photonics, to develop novel VCSEL technology; and in 1998 he co-founded Agility Communications, later acquired by JDSU, to develop widely-tunable integrated optical transmitters. Coldren has authored or co-authored over a thousand papers, 8 book chapters, 2 textbooks, and has been issued 65 patents. He is a Fellow of the IEEE, OSA, and IEE, the recipient of the 2004 John Tyndall Award, the 2009 Aron Kressel Award, and a member of the National Academy of Engineering.
