摘要: 文章利用脉冲激光抽运色散位移光纤,通过自发四波混频过程产生的关联光子对,实验演示了一种光通讯波段的窄带宣布式单光子源.实验测得-3dB带宽为1.1nm单光子场的二阶关联函数g（2）（0）=0.09±0.01,宣布效率可达0.5以上.这种单光子源在量子通信中有潜在的应用前景.

Abstract: According to the correlated photon pairs produced by spontaneous four-wave mixing in dispersion-shifted fiber,we present a telecom-band single-photon source by using mode-locked laser.Single-photons with a -3 dB bandwidth of 1.1 nm are heralded with more than 50% probability.The measured second-order correlation g（2）（0） is equal to 0.09±0.01.Our source is well suit for quantum communication systems.
