Chung-Liang Tang

Electrical and Computer Engineering
Emeritus, Spencer T. Olin Professor of Engineering


Professor Tang was at the Technical University, in Aachen, Germany, as the John Parker Traveling Fellow from Harvard from 1959 to 1960. He was a research staff member, and later principal research scientist in the Research Division of the Raytheon Company from 1960-1964, and joined the Cornell faculty as an associate professor in 1964. He was promoted to full professor in 1968 and held a chaired professorship since 1985. He retired in 2006.

Tang’s primary quest had been to search for and study new optical materials and processes that could be applied to generating, modulating, and detecting electromagnetic radiation from the infrared to the ultraviolet. His primary tool was the laser, but he also developed electro-optic devices, new materials, and original processes to enable his research.

Tang was elected a Fellow of IEEE, the Optical Society of America, and the American Physical Society, and is a member of the National Academy of Engineering. He served on the advisory board for the NTT Basic Research Laboratory in Japan, and received the Charles H. Townes Award from the Optical Society of America.
