摘要:

我们从实验和理论上研究了标准双折射光纤中自发四波混频(SFWM)产生光子对的问题。的能力,以产生一系列的双光子光谱状态,从高度相关的(纠缠),以完全可分解的,通过交叉偏振双折射相位匹配,进行了探讨。一个简单的模型来预测光子对的光谱状态,该模型显示了如何通过选择适当的泵浦带宽、光纤长度和双折射来调节光子对的光谱状态。自发拉曼散射的建模,以确定SFWM和背景拉曼噪声之间的权衡,预测结果与实验数据一致。

英文摘要:

We study both experimentally and theoretically the generation of photon pairs by spontaneous four-wave mixing (SFWM) in standard birefringent optical fibers. The ability to produce a range of two-photon spectral states, from highly correlated (entangled) to completely factorable, by means of cross-polarized birefringent phase matching, is explored. A simple model is developed to predict the spectral state of the photon pair which shows how this can be adjusted by choosing the appropriate pump bandwidth, fiber length and birefringence. Spontaneous Raman scattering is modeled to determine the tradeoff between SFWM and background Raman noise, and the predicted results are shown to agree with experimental data.
