演讲者简介：
Moshe Tur received the B.Sc. in Mathematics and Physics, from the Hebrew University, Jerusalem, Israel (1969), the M.Sc. degree in Applied Physics from the Weizmann Institute of Science, Rehovot, Israel (1973), and his Ph.D. from Tel-Aviv University, Tel-Aviv, Israel (1981). He is presently the Gordon Professor of Electrical Engineering at the School of Electrical Engineering of Tel-Aviv University, Tel-Aviv, Israel, where he has established a fiber-optic sensing and communication laboratory. He authored or co-authored more than 530 journal and conference technical papers with emphasis on fiber-optic sensing (with current emphasis on Structural health Monitoring, using fiber Bragg gratings and the Brillouin and Rayleigh effects), advanced fiber-optic communication systems, as well as on polarization mode dispersion and microwave photonics. Prof. Tur is involved in several international collaborations, including participation in a number of European Projects and activities: INCO, SENARIO (Structural Health Monitoring), SARISTU (Structural Health Monitoring), COST-299 and COST-TD1001. Dr. Tur is a Fellow of both the IEEE and the Optical Society of America.
讲座摘要：
Microwave systems are of the utmost importance in many applications from Radars to spectrum and network analyzers. Quite often, the larger the bandwidth, the better the performance. However, it turns out that as the bandwidth increases electronic microwave components show decreasing performance. Harnessing photonic techniques may help achieving bandwidths, not currently achievable with pure electronic techniques. The talk will introduce the subject, emphasizing photonic true time delay implementations, as well as photonic assisted RF filtering, which takes advantage of polarization pulling, a subject which will be discussed in detail. Tunable optical buffers using linear and nonlinear processing of light will be described and figure of merit of microwave photonics will be mentioned.
