时域有限差分法 理想匹配层 平面光波导 finite difference time domain method perfectly matched layer planar optical waveguide structure
摘要
将理想匹配层(PML)吸收边界条件用于平面光波导结构的时域有限差分法(FDTD)分析,并对微腔体谐振环进行了数值计算模拟.证明了采用PML吸收边界条件的FDTD法应用于平面光波导结构分析的有效性.本方法对平面光波导的计算机辅助设计(CAD)具有实际意义,可用于分析任意复杂结构的平面光波导.
Abstract
The perfectly matched layer (PML) absorbing boundary condition is used in the FDTD analysis of planar optical waveguide structures. The numerical experiments for the Microcavity Ring Resonator are implemented and presented. It is shown that the result is in good agreement with the theoretical solutions. Furthermore, it is proved that this method is valid for planar optical waveguide structure, which can also be used as a powerful CAD tool in the analysis of arbitrary optical waveguide structures.
