摘要:

我们在高非线性光纤(HNLF)中通过自发四波混频(SpFWM)过程产生了1550 nm的相关光子对。对源质量的产生是由符合偶然比(CAR)参数进行评估。实验结果表明,光纤内部产生的自发拉曼散射光子是光源退化的主要原因。然而,对于1.1mW的光纤输入处的泵浦功率,发现CAR值为2.77。

英文摘要:

We generate 1550 nm correlated photon pairs through the spontaneous four-wave mixing (SpFWM) process in a highly nonlinear fiber (HNLF). The pair source quality generation is evaluated by the coincidence-to-accidental ratio (CAR) parameter. It is verified that the spontaneous Raman scattering (SpRS) photons generated inside the fiber contribute to the degradation of the source. Nevertheless, a CAR value of 2.77 is found for a pump power at the input of the fiber of 1.1 mW.
