利用隐式格式，提出了一种新的基于yee网格的有限差分全矢量波束传播方法。该算法通过将传播轴分成两步来实现。利用虚距离法对肋波导的特征模进行了分析。结果表明，该方法在保持与传统的基于yee网格的显式虚距离波束传播方法相同的精度的同时，减少了计算时间和内存。通过对偏振变换器的分析表明，该方法不仅可以用于本征模分析，而且可以用于传播光束的分析。
A novel Yee-mesh-based finite-difference full-vectorial beam-propagation method is proposed with the aid of an implicit scheme. The efficient algorithm is developed by splitting the propagation axis into two steps. The eigenmode analysis of a rib waveguide is performed using the imaginary-distance procedure. The results show that the present method offers reduction in computational time and memory, while maintaining the same accuracy as the conventional explicit Yee-mesh-based imaginary-distance beam-propagation method. It is demonstrated by the analysis of a polarization converter that the present method can be used for not only the eigenmode analysis but also the propagating beam analysis.
