Jungsang Kim, Professor of Electrical & Computer Engineering

Jungsang Kim

Kim received his B.S. degree in Physics in 1992 from Seoul National University (SNU) in Seoul, Korea, graduating with Presidential Honor atop the Natural Science College. He received his Ph.D. in Physics from Stanford University in 1999. His thesis research was on the topic of "Generation and Detection of Heralded Single Photons." He pioneered the research in this exciting area, crucial for realization of secure quantum communications. He worked on the experimental realization of the "Single Photon Turnstile Device," a solid-state photon source capable of generating single photons on demand. He also characterized and demonstrated the performance limits of the "visible light photon counter," which is capable of high quantum efficiency single-and multi-photon detection.

In 1999, he joined Bell Laboratories, Lucent Technologies in Murray Hill, New Jersey. When moving to Bell Labs, he decided to move to a different field of research. He started working on Micro-Electromechanical Systems (MEMS) technology, and contributed to the team building the world's first large-scale all-optical switch using MEMS technology. He helped commercialize Lucent's LambdaRouter All-Optical Switch, and led a team to develop the world's largest all-optical switch that features more than 1,000 input and output ports.

In 2002, he decided to make another jump in the research area, and started working on a technology that will help dramatically improve the coverage of wireless networks inside buildings. He led a team of researchers at Bell Labs to develop RadioStar technology, which enables cost-effective coverage enhancement of CDMA network into buildings. The innovations that enabled RadioStar technology have the potential to dramatically modify the way base transceiver stations for the wireless communication systems are built.
