Title
Semiconductor-laser gain physics: all you want to know and more in 50 minutes
Speaker
Dr. Weng Chow, Sandia National Laboratories, IEEE LEOS Distinguished Lecturer
Abstract
This talk will start by sketching (with more pictures than equations) the formulation of a theory that is based
on a systematic and consistent quantum mechanical description of a semiconductor laser medium. The physical
insight gained from applying the theory will be discussed. Its accuracy and predictive capability will be
demonstrated using examples ranging from microcavity lasers to wide-bandgap and quantum-dot lasers.
Biography
Weng Chow received the Ph.D. degree in physics from the University of Arizona. His dissertation work involved
fluctuation phenomena in quantum optics. At present, he is Distinguished Member of the Technical Staff at
Sandia National Laboratories. Weng Chow's primary research interest is in the application of microscopic theory
to semiconductor laser 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.
Weng Chow also holds the positions of Research Professor of Physics at Texas A&M University, Adjoint Professor
of Optical Sciences at the University of Arizona and Honorary Professor of Physics at Cardiff University. He
has served on the CLEO semiconductor laser program committee and is an associate editor of IEEE Journal of
Quantum Electronics. Weng Chow is a fellow of the Optical Society of America, and recipient of the Dept of
Energy, Basic Energy Science/Material Science Award, the Alexander von Humboldt Senior Scientist Award and the
LEOS Distinguished Lecturer Award.
