主讲嘉宾/Biography:

Zhao Zhang (Member, IEEE) received the B.S. degree from Beijing University of Posts and Telecommunications, Beijing, China, in 2011, and the Ph.D. degree from Institute of Semiconductors, Chinese Academy of Sciences, Beijing, China, in 2016.  From 2016 to 2018, he was with the Hong Kong University of Science and Technology, as a Post-Doctoral Fellow working on the design of ultra-low-jitter PLLs and PAM4 CDRs. From 2019 to 2020, he was with Hiroshima University, Higashi-Hiroshima, Japan, as an Assistant Professor, where he focused on the low-jitter mm-wave PLL for THz communication. In 2020, he joined in the Institute of Semiconductors, Chinese Academy of Sciences, Beijing, where he is currently a Full Professor. He has (co)authored more than 50 academic papers, including several ISSCC/JSSCs. He has gained National Science Fund for Excellent Young Scholars from NSFC. He is the associated editor of IET Electronics Letters, and serves as a reviewer of JSSC/TCAS-I/TCAS-II/TMTT/TVLSI. His research interests include the design of wireline transceivers, low-jitter and low-power PLLs, and ultra-low voltage ICs for bio/energy-harvesting applications.

讲座简介/Abstract:

In my talk, I will present the research activities of our newly established Quantum Optoelectronics Laboratory. I will show how by controlling light-matter interactions at nanometer scale we can create new hybrid excitations called polaritons, which are made of half-light and half-matter. Our research is mainly focused on exploration of the very rich properties of polaritons resulting from the strong coupling of microcavity confined photons with excitons in broad range of organic and inorganic semiconductor materials with primary goal of their use in novel optoelectronic and quantum devices. Utilizing spatial light modulation of excitation laser beam, we can imprint arbitrary two-dimensional lattice trapping potentials to confine spin-polarized polaritonic condensates with tunable inter-site interactions providing exciting opportunities for devising novel and versatile quantum simulation platforms. Furthermore, by implementing annular trapping potentials to confine and control counter-propagating polariton condensates we develop the fundamental element of a quantum computer, a polaritonic qubit.
