Abstract

We report an all-fiber-based experimental setup to generate a correlated photon-pair comb using Four Wave Mixing (FWM) in Highly non-linear fiber (HNLF). Temporal correlations of the generated photons were confirmed through coincidence measurements. We observed a maximum of 32 kcps, with a coincidence to accidental ratio of

$17 \pm 1$

. To further understand the underlying processes, we also simulated a generalized FWM event involving the interaction between an arbitrary frequency comb and a Continuous Wave (CW) pump. non-linear dynamics through the HNLF were modelled using Schrödinger propagation equations, with numerical predictions agreeing with our experimental results.

我们报告了在高非线性光纤（HNLF）中利用四波混合（FWM）产生相关光子对梳的全光纤实验装置。通过巧合测量确认了生成光子的时间相关性。我们观测到的最大值为 32 kcps，巧合与意外的比率为 17 \pm 1$。为了进一步了解其基本过程，我们还模拟了一个涉及任意频率梳和连续波（CW）泵浦之间相互作用的广义全波调制事件。使用薛定谔传播方程模拟了通过 HNLF 的非线性动力学，数值预测与我们的实验结果一致。
