Abstract

We experimentally study Bragg-scattering four-wave mixing in a highly nonlinear fiber at telecom wavelengths using photon counters. We explore the polarization dependence of this process with a continuous wave signal in the macroscopic and attenuated regime, with a wavelength shift of 23 nm. Our measurements of mean photon numbers per second under various pump polarization configurations agree well with the theoretical and numerical predictions based on classical models. We discuss the impact of noise under these different polarization configurations.

摘要

我们使用光子计数器对电信波长下高非线性光纤中的布拉格散射四波混频进行了实验研究。我们在宏观和衰减状态下，利用连续波信号，以23纳米的波长偏移，探索了该过程的偏振依赖性。我们在各种泵浦偏振配置下对每秒平均光子数的测量结果与基于经典模型的理论和数值预测吻合良好。我们讨论了在这些不同偏振配置下噪声的影响。
