New optics center featured at international symposium

James Hwang, professor of electrical and computer engineering, was a member of the steering committee that organized this year's International Microwave Symposium in Philadelphia from June 8-13.

The symposium, the largest conference of the Institute of Electrical and Electronic Engineers (IEEE), was attended by more than 10,000 people. Sergey Cherepko, who earned his Ph.D. from Lehigh in May, presented a paper titled "Implementation of NQS Effects in Large-Signal BJT Models," which was co-authored by Hwang. Cherepko is now a visiting research scientist with Hwang's research group at Lehigh.

Hwang's group was among the approximately 500 companies and institutions that exhibited at the symposium. The Lehigh exhibit highlighted the university's two-year-old Center for Optical Technologies and did a real-time demonstration of innovative wireless links for local area networks.

Also attending the symposium were Choi Law, Bill Jemison and Sergiy Osynskyy, visiting research scientists; and Liangjun Lei, Mamour Ba, Marvin Marbell, Xiaobin Yuan, and Zhengnan Zhang, who are Ph.D. candidates studying with Hwang. Li Jiang, a Ph.D. candidate studying with Richard Decker, professor of electrical and computer engineering, also attended.
