Hong Tang - Integrated nonlinear photonics for quantum frequency conversion

Tuesday, September 10, 2019 at 12:15pm to 1:15pm

Phillips Hall, 233

Hybrid quantum networks rely on faithful quantum state transfer between disparate physics elements operating at dissimilar frequencies. Quantum frequency conversion bridges their frequency gaps by coherently manipulating the carrier frequency while maintaining the quantum correlations. The efficiency of frequency conversion is dictated by photon-photon interaction in a nonlinear optical media which is typically weak. In this talk, I will show material and device engineering on an integrated photonic platform where the nonlinear photon-photon coupling can be greatly enhanced. Specifically, I will show (1) coherent conversion of light between visible and telecom wavelengths; (2) noise-free frequency shift of photon within telecom band; and (3) microwave-to-optical frequency conversion that promises to link superconducting quantum circuits and room temperature fiber-coupled quantum systems.

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.
