Frequency-bin Entangled Comb of Photon Pairs From a Silicon-on-Insulator Micro-Resonator



Jun Chen, Zachary H. Levine, Jingyun Fan, Alan L. Migdall


We present a quantum-mechanical theory to describe narrow-band photon- pair generation via four-wave mixing in a Silicon-on-Insulator (SOI) micro- resonator. We also provide design principles for efficient photon-pair generation in an SOI micro-resonator through extensive numerical simulations. Microring cavities are shown to have a much wider dispersion-compensated frequency range than straight cavities. A microring with an inner radius of 8 µ m can output an entangled photon comb of 21 pairwise peaks (42 comb lines) spanning from 1.3 µ m to 1.8 µ m. Such on-chip quantum photonic de- vices offer a path toward future integrated quantum photonics and quantum information processing.
