本文介绍了实际单模光导纤维中存在的模式偏振效应(双折射效应),着重解释了偏振状态(Sop)的Poincafe＇球描述方法及其特点。并对这方面的研究工作做了一些初步的评述。
In this paper, the mode polarization effect (birefringence effect) existing in the actual single-mode optical fiber is introduced. The description of Poincafe ’sphere describing the polarization state (Sop) and its characteristics are mainly explained. And made some preliminary comments on the research work in this field.
