Alex Wai

Alex Wai received the Bachelor of Science (Hons) degree in Physics with first class honours from the University of Hong Kong in 1981.  He obtained his Ph.D. degree from the University of Maryland, College Park, Maryland, in 1988.  His thesis research was on the propagation of nonlinear optical signals in optical fibers. After graduation, he joined Science Applications International Corporation (SAIC) in McLean, Virginia, United States to work on the Tethered Satellite System (TSS) mission – a joint U.S.-Italy Space Shuttle project to study the release and retrieval of a satellite tethered to the Space Shuttle with a 20-kilometer long cable. 

In 1990, Prof. Wai returned to University of Maryland in the Department of Electrical Engineering.  There he resumed his research on fiber optic communication focusing on transoceanic transmission.  In 1996, Prof. Wai returned to Hong Kong to join the Department of Electronic Engineering of The Hong Kong Polytechnic University.  In Hong Kong, Professor Wai began his research on future optical network.  He designed and demonstrated routing of optical information with all-optical processing of the packet header information.  He has received seven U.S. patents on his inventions in optical packet-switching and other technologies. Currently, he served as the Vice President (Research Development) and Chair Professor of Optical Communications.

Prof. Wai is an active contributor to the technical field and had served in the organization and program committees of many international conferences.  Professor Wai is a Fellow of Optical Society of America and a Fellow of IEEE.

For JLT he is handling submissions on the following topics:

  • Fiber-optic transmission system design and modeling
  • Theory and modeling of lasers
  • Nonlinear propagation
  • Packet and burst switching
  • Network theory
  • Access network architectures and devices
