摘要

本文提出了一种监测光传输系统偏振态（SOP）变化速度的综合方法。利用时频特征提取极化支路功率。该方法既可以在不使用MIMO模块的接收机数字信号处理器（DSP）中实现，也可以在硬件简单的光纤跨节点上实现。在2000公里的光纤链路中进行了验证，可以监测20mrad /s或以上的SOP变化速度。

SOP Monitoring Using Time-Frequency Feature Extraction of the Polarization Tributary Powers

This letter proposes a comprehensive method to monitor the change speed of the state of polarization (SOP) for optical transmission systems. By using time-frequency feature extraction of the polarization tributary powers. The proposed method can be implemented either in the receiver digital signal processor (DSP) without using the MIMO module or at any fiber span nodes with simple hardware. It was validated in a 2000 km fiber link and can monitor within or exceeding 20 Mrad/s SOP change speed.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
