对脉冲泵浦下色散位移光纤中产生的光子对的光谱相关进行了理论分析和实验研究。我们首先在接近真实的实验条件的假设下，根据推导的自发四波混频双光子态，计算了光子对的光谱函数。利用光子相关测量方法对光纤中产生的信号光子对和闲频光子对的光谱特性进行了实验研究，实验结果与理论计算相吻合。该研究对于发展基于光纤的纠缠光子对源和研究多光子对的多光子量子干涉是有用的。
Spectral correlation of photon pairs generated in dispersion shifted fiber by a pulsed pump is theoretically analyzed and experimentally investigated. We first calculate the spectral function of photon pairs according to the deduced two-photon state generated by spontaneous four wave mixing under the assumptions close to the real experimental conditions. We then experimentally study the spectral property of the signal and idler photon pairs generated in optical fiber by photon correlation measurements, and the experimental results agree with the calculation. The investigation is useful for developing fiber-based sources of entangled photon pairs and for studying multi-photon quantum interference with multiple photon pairs.
