Abstract

We demonstrate the generation of quantum-correlated photon pairs from a Si photonic-crystal coupled-resonator optical waveguide. A slow-light supermode realized by the collective resonance of high-Q and small-mode-volume photonic-crystal cavities successfully enhanced the efficiency of the spontaneous four-wave mixing process. The generation rate of photon pairs was improved by two orders of magnitude compared with that of a photonic-crystal line defect waveguide without a slow-light effect.

摘要

我们展示了从硅光子晶体耦合谐振器光波导中产生量子关联光子对的过程。由高Q值和小模式体积光子晶体腔的集体共振实现的慢光超模式成功提高了自发四波混频过程的效率。与没有慢光效应的光子晶体线缺陷波导相比，光子对的产生率提高了两个数量级。
