平面光波导数值分析的一种新方法

A Novel Nuerical Method of Optical Planar Waveguide

用有限时域差分法直接求解了依赖时间的麦克斯韦旋度方程 ,得到了一维电磁场的有限时域差分公式。在此基础上 ,利用吸收边界条件计算了简单三层对称平面光波导中TE模的光场分布 。

The time dependent Maxwell curl equation is directly solved by Finite Differences Time Domain method(FD-TD) in this paper.And finite differences time domain formula of one dimensional electromagnetic field is also derived,based on which the optical field distribution of TE mode in three layer symmetry planar waveguide is calculated suing absorbing boundary conditions and the optical field distribution of arbitrary profile is obtained.
