DenBaars is a Distinguished Professor of Materials and Electrical & Computer Engineering at UCSB, where he serves as director of the Institute for Energy Efficiency and co-director of the Solid State Lighting and Energy Electronics Center (SSLEEC).
He received his BS in materials and metallurgical engineering from the University of Arizona, graduating as Valedictorian of the College of Engineering, and earned his MS and PhD in engineering from the University of Southern California. He began his career at Hewlett-Packard’s Optoelectronics Division, developing high-brightness LED technologies, before joining the UCSB faculty. He has played a pivotal role in advancing GaN-based optoelectronics and strengthening academic–industry collaboration that has helped shape modern semiconductor innovation.
DenBaars is a pioneer in compound semiconductor optoelectronic materials and devices whose research is said to have fundamentally influenced modern photonic technologies. His work has addressed key challenges in crystal growth, defect reduction and device architecture, leading to major improvements in the efficiency, brightness and reliability of light-emitting diodes and laser diodes. These advances underpin solid-state lighting, high-resolution LED and laser displays, ultraviolet light sources, and emerging optical communication systems.
DenBaars played a central role in establishing gallium nitride (GaN) as a viable and scalable industrial technology, delivering substantial economic and environmental benefits. His contributions enabled the widespread adoption of high-efficiency LED lighting across general illumination, automotive lighting, and display applications, accelerating the transition from energy-intensive legacy lighting to sustainable solid-state solutions while advancing fundamental understanding of GaN materials and device physics.
Together with Shuji Nakamura, Umesh Mishra and James Speck, DenBaars co-founded SSLEEC at UCSB, now the world’s leading academic center for solid-state lighting and III-nitride research, says Optica. His pioneering work on micro-LEDs and GaN lasers has further enabled breakthroughs in next-generation displays, optical data storage, projection systems, and laser-based lighting.
He is a Fellow of Optica, IEEE, and the National Academy of Inventors. His additional awards include the Aron Kressel Award, Japanese Science of Applied Physics (JSAP) Outstanding Paper Award, and the Viterbi Award for USC Distinguished Alumni.
Established in 1997, the Holonyak Jr Award recognizes significant contributions to optics based on semiconductor-based optical devices and materials, including basic science and technological applications. It honors Nick Holonyak Jr’s distinguished contributions to the field of optics through the development of semiconductor-based light-emitting diodes and semiconductor lasers. The award is endowed by SDL Ventures LLC, and Donald and Carol Scifres.
