Zhao, Jianye is a professor in the Department of Electrical Engineering, School of EECS, and has served as the Deputy Director of Institute of Applied Electronics since 2012. He obtained his B.Sc. from Fudan University in 1993, M.Sc. from Peking University in 1996, and Ph.D. from Peking University in 1999 respectively. His research interests include chip-scale atomic clock, frequency standard, optical frequency comb and photoelectric neural computing.
Dr. Zhao has publishes more than 110 research papers, including 46 SCI papers. These SCI paper are published in top-tier journals, including 9 papers published in journals of IEEE, 22 papers published in journals of Physical Review series and journals with influence factors above 3. SCI papers are cited 221 times by other researchers. He has undertaken more than 10 research programs, including 4 programs supported by NSFC, 2 programs supported by 863 project. Dr. Zhao is serving as the academic committee member of Circuit & System Branch in Chinese Institute of Electronics, and is also in the Editorial Board of Journal of Electronics &Information Technology. He was awarded Higher Education Science and Technology Progress First Prize by Ministry of Education of China in 2006.
Dr. Zhao’s research achievements are summarized as follows:
1) Chip-scale atomic clock techniques: The atomic clock based on light-atom interaction is the forefront of quantum technology, and the study on chip-scale coherent population trapping (CPT) atomic clock is very important to the Global Navigation Satellite System. Dr. Zhao carries out research on basic theories and key technologies of the chip-scale CPT atomic clock, and promotes their applications. He achieves the chip-scale atomic clock which has the best long-term stability among clocks reported in the world, by exploring the feedback mechanism between light and modulation microwave. The practical chip-scale atomic clock has passed all kinds of space environment experiments, and it will be equipped on the satellite.
2) Frequency standard: Dr. Zhao proposes the idea of optical comb-atomic clock integration, and preliminarily demonstrates the CPT optical frequency comb and the rubidium two-photon frequency standard. The microwave signal is obtained from optical frequency directly and distributed over fiber links. Based on these achievements, he took part in the proposal of time-frequency dissemination methods in Square Kilometer Array (SKA) Project.
3) Photoelectric neural computing: Dr. Zhao applies the optical comb in the field of ultrafast optical computing. He implemented the optical spike-timing-dependent plasticity (STDP) mechanism based on CPT optical frequency comb, and simulated the memory and learning process of the brain.
