Nanophotonic integrated circuits with 1% single-photon nonlinearity

Mengdi Zhao, Kejie Fang

Research output: Chapter in Book/Report/Conference proceedingConference contribution


We realize nanophotonic integrated circuits in thin-film InGaP with a record-high second-order optical nonlinearity over 1%, measured by the ratio between single-photon coupling rate (g/2π = 8.3 MHz) and intrinsic cavity photon loss rate.
