Prem Kumar

Professor of Electrical and Computer Engineering; Professor of Physics & Astronomy

Ph.D., SUNY at Buffalo, 1980; M.Sc. Physics, Indian Institute of Technology, Kanpur, India, 1976; B.Sc. Physics, University of Delhi, Delhi, India, 1974

Research Interests

Kumar group’s research is conducted under the umbrella of the Center for Photonic Communication and Computing in the ECE department. The Center conducts cutting edge fundamental science and engineering research leading to the development of advanced photonic systems for communication and computing. The focus is on optical and optoelectronic systems that push the technological limits to ever increasing speeds (currently targeting terabit per second range) or levels of integration (nanophotonic devices) or that exploit the fundamental laws of nature to accomplish communication, signal processing, and computing in radically new ways (quantum communications and computing with photons).
