Resume of Career

Chester Shu received his M.S. and Ph.D. degrees in Applied Physics from Columbia University in the city of New York in 1986 and 1991, respectively. He joined the Department of Electronic Engineering at CUHK in 1992 and became a full Professor in 2003. His current research focuses on fiber communications, particularly in nonlinear fiber optics and ultrafast processing of optical communication signals. He has made original contributions to optical processing with specialty fibers and has developed unique approaches to process signals with diverse bit rates, modulation formats, and polarizations. Previously, Chester worked on the optoelectronic generation, guided-wave transmission, and detection of picosecond pulse signals in his graduate research. He developed experiences on the design and characterization of multiple quantum-well semiconductor lasers while working as a graduate intern at Siemens Corporate Research Laboratories at Princeton. Before joining CUHK, he worked at a startup in Seattle and performed research on integrated electro-optic polymer waveguide modulators for photonic switching.

Chester has authored/coauthored over 300 research papers and delivered a number of technical talks. He was a topical editor of Optics Letters in the area of optical fiber communications in 2005-2011 and has served in a number of technical program committees including OFC/NFOEC and LEOS. He was the Chairman of IEEE Hong Kong LEOS (now Photonics Society) Chapter in 2006 and 2007.
