Biography

 

            Dr. Kwong’s research interests include optical coding theory, optical multiple-access systems and networks, ultrafast all-optical signal processing techniques, and wireless communications. He has co-authored the first-of-its-kind technical book on optical coding theory and its applications to code-division multiple access (CDMA), Prime Codes with Applications to CDMA Optical and Wireless Networks (Norwood, MA: Artech House), in 2002. He has contributed one chapter on optical codes to another technical book, Optical Code Division Multiple Access: Fundamentals and Applications (Boca Raton, FL: Taylor & Francis), in 2006. In 2013, he has also coauthored the first classical reference book on optical coding theory, Optical Coding Theory with Prime (NY: CRC Press, 2013). He has published over 160 professional articles, and chaired technical sessions and served technical program committees in international conferences. He has given seminars and tutorials in optical coding theory and its applications in various cities and countries, such as Montreal (Canada), Hong Kong (China), Seoul (South Korea), Hsinchu and Taichung (Taiwan), and Princeton (NJ, United States).

 

         His accomplishments in this emerging field of optical coding theory began as early as 1990. Since then, he has played a leading role to its advancement. He is internationally recognized as a pioneer and renowned expert in the field. His accomplishments include

*      Construction of optical codes for various applications with scalable and flexible code parameters, properties, cardinality, and performance;

*      Improvement in analytical techniques on code performance;

*      Development of novel algebraic coding techniques supported by latest hardware technologies;

*      Pioneering the research of quality-of-service (QoS) control and service prioritization in multirate, multimedia optical systems with his famous “multilength” optical codes.

Especially in the last category, the impact is prominent as future optical systems are expected to support multimedia services with different bit rates, QoSs, and priorities.

 

         An important contribution that distinguishes Dr. Kwong from others is his discovery of a series of algebraic coding techniques using Galois (prime) field. These techniques provide straightforward and systematic ways to generate vast families of “prime” codes that are scalable and flexible in the choices of code parameters, properties, cardinality, and performance, as opposed to exhaustive computer-search or geometry coding algorithms. Dr. Kwong is one of the pioneers in the mid-90s directing research momentum from 1D coding to muiltidimenisonal coding that is more flexible and scalable, and promotes the practicality of optical coding systems.

 

         Photonics is a field dominated by experiments mostly targeted at the physics of devices. Dr. Kwong’s contributions stand out in this field because they have been derived under an analytical framework with a sound theoretical foundation and have proven to be applicable in practice. An example is the special 2D prime codes he designed for Princeton’s state-of-the-art optical-CDMA testbed in a multiyear, multimillion-dollar project funded by the US DARPA in the 2000-2007. In the project, Dr. Kwong was a co-PI, in charge of optical coding theory, with the team led by Prof. P.R. Prucnal of Princeton University. With the support of his codes, the testbed operated at 10 Gbit/s and was scalable to support at least 1,000 subscribers and 100 simultaneous users with 10^{-9} bit-error-rate, pushing the limit of the latest technology at that time.

 

         Dr. Kwong is a senior member of the IEEE. He was an associate editor of the IEEE Transactions on Communications and the recipient of the NEC Graduate Fellowship awarded by the NEC Research Institute, Princeton, USA, in 1990 and 1991. He has received the Young Engineer Award from the IEEE (Long Island Chapter) in 1998. In 2016, he has received the Teacher of the Year award from the School of Engineering and Applied Sciences at Hofstra University.
