Abstract
Quantum nanophotonics and plasmonics are exciting fields where I specialize, particularly in exploring low-dimensional materials. My research focuses on three main concepts: quantum effects, nonlinearity, and coherence. I'll share insights from three research areas: metallic quantum wells, quantum gap phenomena, and quantum emitters. I'll explain how we harness extreme nonlinearity from metallic quantum wells and achieve single-photon frequency conversion based on design of plasmonic density of state. Plus, I'll present our latest findings on high-speed photon emission and GHz-rate single-photon sources. Looking ahead, my aspiration is to establish a sophisticated quantum optics laboratory capable of performing cutting-edge, ultrafast, ultra-sensitive, and multi-dimensional measurements, serving as a hub for exploring and harnessing quantum phenomena for innovative optical applications in AI chips, quantum communication and computation.
