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。
Through the discussion of the basic theory of optically active fiber, the basic parameters and electromagnetic field components of the optically active fiber are analyzed by using ε as an independent variable, and the corresponding calculation chart is obtained. In addition, by measuring and further analyzing the rotation angle of the actual rotating optical fiber, it is demonstrated that there is a simple and definite linear relationship between ’ε and the bias magnetic field. This makes the original complex tensor dielectric constant matrix solution becomes very simple.
