He worked on the problem of He-Ne laser modulation, the transmission of laser light for optical communication and photo thermal effects. Later he changed his research field to quantum electronics and opto-electronics. He co-authored the classic textbook, Fields and Waves in Communication Electronics, before he had a doctoral degree while working 6 days a week in microwaves at General Electric during WW II. His current research interest is communications applications of lasers, with emphasis on short-pulse phenomena. |
