相干光通信系统偏振噪声的理论模型和实验研究

The Theory Model and Experiment Research About Optical Polarization Noise in the Coherent Fiber Communication System

光学系统偏振噪声的抑制是相干光通系统中的关键技术之一。本文首次提出光纤在线工艺法偏振控制方案,建立了相应的理论模型,并开展了实验研究。实验结果表明该方案是有效可行的。

One of the key technology in coherent optical communication system is how to restrain polarization noise of the optical system. The paper puts forward the scheme controlling polarized state by means of on-line optical fiber technics. Corresponding theory model has been established, and experiment al research has been already carried out. On the basis of the experiment, we confirm that the scheme is more effective and feasible.
