偏振复用载波的自零差系统提供了一种具有简化信号处理要求的无LO相干接收机，是高速短距离数据中心互连的一个很好的候选者。这些系统的实际实现受到接收端分离载波和调制信号的偏振控制要求的限制。本文对基于极化分集的系统中极化损伤的影响进行了研究和建模。针对偏振复用载波系统，提出了一种新颖实用的基于单偏振光功率反馈的自适应偏振控制技术，并通过仿真进行了验证。实验证明了该概念在偏振复用载波QPSK系统中的应用。

英文摘要：
  Self-homodyne systems with polarization multiplexed carrier offer an LO-less coherent receiver with simplified signal processing requirement that can be a good candidate for high-speed short-reach data center interconnects. The practical implementation of these systems is limited by the requirement of polarization control at the receiver end for separating the carrier and the modulated signal. In this paper, effect of polarization impairments in polarization diversity based systems is studied and modeled. A novel and practical adaptive polarization control technique based on optical power feedback from one polarization is proposed for polarization multiplexed carrier based systems and verified through simulation results. The application of the proposed concept is experimentally demonstrated also for a QPSK system with polarization multiplexed carrier.
