我们报道了在室温下从色散工程的硅光子晶体波导中产生电信C波段的相关光子对。产生光子对的自发四波混频过程通过使有源器件长度小于100 μ m的慢光传播而增强。在每脉冲0.006的对产生率下，这种超紧凑光子对源的符合率为12.8，为实现可扩展的量子信息处理铺平了道路。(C)2011年美国光学学会
We report the generation of correlated photon pairs in the telecom C-band at room temperature from a dispersion-engineered silicon photonic crystal waveguide. The spontaneous four-wave mixing process producing the photon pairs is enhanced by slow-light propagation enabling an active device length of less than 100 mu m. With a coincidence to accidental ratio of 12.8 at a pair generation rate of 0.006 per pulse, this ultracompact photon pair source paves the way toward scalable quantum information processing realized on-chip.
