摘要:

我们报道了在室温下,从色散工程硅光子晶体波导中产生的电信C波段的相关光子对。产生光子对的自发四波混频过程被慢光传播增强,使得有源器件长度小于100 μm。在每脉冲0.006的对产生率下,具有12.8的符合与偶然比率,这种超紧凑光子对源立即适用于在芯片上实现的可扩展的量子信息处理。

英文摘要:

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 μm. With a coincidence to accidental ratio of 12.8, at a pair generation rate of 0.006 per pulse, this ultra-compact photon pair source is immediately applicable towards scalable quantum information processing realized on-chip.
