The Effect and Evaluation of ε′for Rotatory Characteristic in a Rotatory Optical Fiber

通过对旋光光纤基本理论的讨论 ,以′ε为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′ε与偏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 Yε′ 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 Yε′ and bias magnetic field H b was demonstrated, by that the tensor dielectric coefficient of the rotatory optical fiber can be easily eveluated.
