本文对单模光纤中线偏振面的旋转与光纤几何路径的关系进行了研究.首次报道了在光纤入射端和出射端不平行的情况下的数值计算和实验测量结果. In this paper, the relationship between the rotation of linear polarization plane and the optical fiber geometry in single-mode fiber is studied, and the numerical calculation and experimental measurement results are reported for the first time when the incident and outgoing ends of fiber are not parallel.
