Xiyuan Lu

Xiyuan Lu is a PML/UMD Postdoctoral Researcher in the Microsystems and Nanotechonology Division. He received a B.S. in Physics from Nanjing University, China and a Ph.D. in Physics from University of Rochester. His doctoral research focused on developing and characterizing entangled photon sources and heralded single photon sources in high-quality silicon microresonators, and on fabricating silicon carbide micro/nanophotonic devices for optomechanical and nonlinear optical applications. He is now working with Kartik Srinivasan in developing chip-scale nonlinear photonic devices such as microcavity frequency combs, and in optimizingsignal transduction in integrated electro-optomechanical systems.
