Abstract
Lightwave communications is a major engineering innovation that revolutionized the telecom industry. Innovations in optical fiber and photonics technologies continue to advance lightwave communications, which encompasses both telecom and datacom, thus enabling the inexorable growth of the Internet, a key element of the information age. This talk will present a perspective on advancements in lightwave communications, discuss network requirements and traffic demands that drive innovations in photonics technologies and systems, and consider various innovative advances that fuel the continuing evolution of communications networks toward larger capacity, greater flexibility, enhanced functionality, higher energy-efficiency and lower cost.
Biography
Tingye Li retired in December, 1998 as a Division Manager in the Communications Infrastructure Research Laboratory of AT&T Labs in New Jersey. He is now an independent consultant in the field of lightwave communications and serves on the board of directors of several optical component and systems companies. Since joining AT&T Bell Laboratories in 1957, he has worked in the areas of antennas, microwave propagation, lasers, photonics technologies, and optical communications. His early work on laser resonator modes established the basic theory of laser modes and is considered a classic. Since the late 1960s, he and his groups have been engaged in pioneering research on lightwave technologies and systems, which have been commercialized and deployed in telecom infrastructures worldwide. During the 1990s, he led the seminal work with his colleagues on amplified wavelength-division-multiplexed (WDM) transmission technologies and systems, which revolutionized lightwave communications and facilitated the exponential growth of the Internet.Dr. Li holds a B.Sc. degree from the University of Witwatersrand in South Africa, and M.S. and Ph.D. degrees from Northwestern University in Evanston, IL. He is a Fellow of OSA, IEEE, AAAS, PSC, and IEC, a Member of the National Academy of Engineering and Academia Sinica, and a Foreign Member of the Chinese Academy of Engineering. He has received the IEEE 1975 W. R. G. Baker Prize, the IEEE 1979 David Sarnoff Award, the OSA/IEEE 1995 John Tyndall Award, the OSA 1997 Frederic Ives Medal/Jarus Quinn Endowment, the 1997 AT&T Science and Technology Medal, the IEEE 2004 Photonics Award, and the IEEE 2009 Edison Medal. His other awards include the 1981 Alumni Merit Award from Northwestern University, and Achievement Awards from CIE/USA (1978), CAAP (1983) and PSC (1998). He has been named an honorary professor at many universities and institutions in China and Taiwan, and has been granted an Honorary Doctor of Engineering degree by the National Chiao Tung University in Taiwan and an Honorary Doctor of Science Degree in Engineering from the University of the Witwatersrand in South Africa. Dr. Li has been active in various professional societies, serving as officer, board member, committee member and chair, journal editor, conference chair, etc. He was President of OSA in 1995.
