We present a quantum-mechanical theory to describe narrowband 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 μm can output an entangled photon comb of 21 pairwise-correlated peaks (42 comb lines) spanning from 1.3 μm to 1.8 μm. Such on-chip quantum photonic devices offer a path toward future integrated quantum photonics and quantum integrated circuits.
我们提出了一种量子力学理论，用于描述通过绝缘体上硅（SOI）微谐振器中的四波混频产生窄带光子对。我们还通过广泛的数值模拟，给出了在SOI微谐振器中高效产生光子对的设计原则。结果表明，微环腔的色散补偿频率范围比直腔宽得多。一个内半径为8μm的微环可以输出一个纠缠光子梳，该光子梳有21个两两相关的峰（42条梳状线），波长范围从1.3μm到1.8μm。这种片上量子光子器件为未来的集成量子光子学和量子集成电路提供了一条途径。
