通过对旋光光纤基本理论的讨论,以????Yε′?Ｎ?自变量对旋光光纤的基本参量和电磁场分量进行了数值分析,得出了相应的计算图表。另外,通过对实际的旋光光纤进行旋光角测量和进一步分析,论证了??Yε′?Ｓ肫?置磁场之间具有简单而明确的线性关系。这使得原本复杂的张量介电常量矩阵的求解变得非常简单。

The basic theory of a rotatory optical fiber was discussed. The electromagnetic field components, fundamental parameters of the fiber were evaluated as the functions of the argument ε′ which is the rotatory element of the tensor dielectric coefficient matrix ε of the fiber. The calculating results were shown by the curves. In addition, a new expression about the relation between ε′ and bias magnetic field H b was demonstrated, by that the tensor dielectric coefficient of the rotatory optical fiber can be easily eveluated.
