Education:

Ph.D., 1999, Electrical Engineering, Princeton University

M.A., 1997, Electrical Engineering with minor in Computer Engineering, Princeton University

M.S., 1995, Physics, University of Science and Technology of China (USTC)

B.S., 1992, Physics, University of Science and Technology of China (USTC) After his Ph. D., Dr. Yang joined Bell Laboratories, Lucent Technologies Inc., in 1999, as Member of Technical Staff doing research in photonic networks, especially in advanced optical channel monitoring for SONET, monolithic active-passive integrated III-V photonic devices, and high-speed, low jitter, multi-spatial-mode passive mode-locked semiconductor lasers. Before joining Western in Fall 2007, he was a Principal Engineer, Lightwave Systems, Ciena Corp., leading research and development in fiber polarization mode dispersion (PMD).  His current research interest focuses on low loss metamaterials and its applications to photonic and optoelectronic devices. He has published 25 journal papers and 33 conference papers and holds 9 U. S. patents awarded or pending.
