摘要
研究了法拉第旋转镜用于补偿单模光纤中1 550 nm单光子传输的偏振漂移特性.比较了不同平均光子数下经由不同长度单模光纤传输后单光子偏振漂移的差异,以及使用法拉第旋转镜的偏振漂移抑制比.实验结果表明,在50 km光纤50 kcps光子计数(光强)下偏振漂移改善最优,偏振漂移抑制比达25.3.
Abstract
The research on polarization compensation characteristics of single photon transmission in the single-mode fiber was presented by using Faraday rotator mirror.It is found that the difference results for the polarization drifting compensation with different fiber lengths of and different photon intensities.In addition,the polarization drifting with and without the Faraday rotator mirror was measured.The result shows that the optimal suppression ratio could be up to 25.3 at 50 kcps using 50 km fiber.
