11月9日Hong Tang报告

发布时间:2018-11-07

报告时间:11月9日 周五  上午9:00

报告地点:实验室一楼会议室

报告人:Hong Tang教授 (耶鲁大学)

报告题目: Integrated chi(2) photonics

报告摘要: 

     The ability to generate and manipulate photons with high efficiency and coherence is of critical importance for both fundamental quantum optics studies and practical device applications. However mainstream integrated photonic platforms such as those based on silicon and silicon nitride lack the preferred cubic c(2) nonlinearity, which limits active photon control functionalities. In this talk, I will present integrated photonics based on aluminum nitride (AlN), whose wurtzite crystal structure gives rise to the strong second-order optical nonlinearity and piezoelectric effect. Together with its low optical and mechanical losses, the integrated AlN photonics can provide enhanced c(2) photon-photon interactions to achieve high fidelity photon control, including on-chip parametric down-conversion, coherent light conversion, spectral-temporal shaping, and microwave-to-optical frequency conversions.

报告人简介: 

     Hong Tang is the Llewellyn West Jones, Jr. Professor of Electrical Engineering, Physics and Applied Physics at Yale University. He obtained his B.S. degree at the University of Science and Technology of China and Ph.D. at Caltech. His research utilizes integrated photonic circuits to study photon-photon, photon-mechanics and photon-spin interactions as well as quantum photonics involving microwave and optical photons. He has been on Yale faculty since 2006. He is a recipient of the NSF CAREER Award and Packard Fellowship in Science and Engineering.
