As a principal scientist at PARC, Christopher Chua is the technical principal investigator for the team developing semiconductor optical emitters -- light-emitting diodes (LEDs) and lasers. He is currently focusing on epitaxy, design, and fabrication of nitride-based visible and ultra-violet LEDs and laser diodes. At PARC, Christopher designed and built the world's most densely packed vertical cavity surface-emitting laser (VCSEL) arrays, and pioneered a VCSEL architecture that is currently used by leading manufacturers. He also conceptualized a new type of micro-machined (MEMs) inductor, and worked with a team to demonstrate world-record integrated circuit oscillator Q-factors utilizing this device. Dr. Chua earned his Ph.D. in Electrical Engineering from Cornell University, and a B.S. in Physics as well as a B.S. in Electrical Engineering from the Massachusetts Institute of Technology (M.I.T.). He has authored numerous technical papers in leading scientific journals, including co-authoring papers that won the best paper award at the 2003 ISSCC (International Solid State Circuit Conference) and at the 2009 IMAPS (International Microelectronics and Packaging Society). Christopher holds more than 90 U.S. patents.
