光的偏振态（SOP）的控制仍然是光通信中的开放问题之一。特别是，SOP稳定的实现可以在先进的光通信系统中找到许多应用：从偏振模色散的缓解到新型多级调制格式的开发。在本文中，偏振稳定的理论和实验方面的处理，并提出了一种新的算法，以克服与有限范围的双折射组件的实际可用性的问题，并解决了无尽的稳定的要求。一个完整的分析的控制算法，琼斯矩阵形式主义的基础上，也提出。偏振稳定器的实际实施进行了讨论，并显示基于液晶和磁光延迟器的实验演示。
The control of the state of polarization (SOP) of light remains one of the open issues in optical communications. In particular, the achievement of a stabilization of the SOP can find many applications in advanced optical communication systems: from the mitigation of polarization-mode dispersion to the development of novel multilevel modulation formats. In this paper, theoretical and experimental aspects of polarization stabilization are dealt with, and a novel algorithm to overcome the issues related to the practical availability of finite-range birefringent components and to solve the requirement for endless stabilization is also presented. A complete analysis of the control algorithm, based on the Jones matrix formalism, is also presented. The practical implementation of the polarization stabilizer is discussed, and experimental demonstrations based on liquid crystal and magnetooptical retarders are shown.
