Weng Chow


Weng Chow received the Ph.D. degree in physics from the University of Arizona. He was an Associate Professor of Physics and Astronomy at the University of New Mexico before joining Sandia National Laboratories, where he is a Distinguished Member of the Technical Staff. Weng Chow’s primary research interest is in the application of microscopic theory to optoelectronic device development. Some of this work is described in two texts, Semiconductor-Laser Physics and Semiconductor-Laser Fundamentals: Physics of the Gain Materials. His other interests include laser gyros, phased arrays, coupled lasers, quantum optics and optical ignition of pyrotechnics. Dr. Chow is an Adjunct Professor of Optical Sciences at the University of Arizona, Research Professor at Texas A&M University, and Honorary Professor of Physics at Cardiff University, Wales. He is a fellow of the Optical Society of America, and received the 1998 Dept of Energy, Basic Energy Science/Material Science Award and a 2003 Alexander von Humboldt Forschungspreis.
