摘 要: | 将基于Daubechies紧支集尺度函数的时域多分辨分析(MRTD)算法用于集成平面光波导组件的时域分析中,实现了MRTD算法的各向异性理想匹配层(APML)吸收边界条件,并对平行介质带定向耦合器进行了数值模拟和验证,所得结果与解析解非常一致.与传统的FDTD算法相比,MRTD算法在不牺牲计算精度的前提下能够大大节省计算资源.

Abstract: | The mutiresolution time-domain (MRTD) method based on Daubechies′ compactly supported scaling functions has been applied in the time-domain analysis of integrated planar optical waveguide components. The anisotropic perfectly matched layer (APML) absorbing boundary condition for MRTD method has been implemented. The numerical simulations for the parallel-slab directional coupler are presented and the computing results using this scheme are in highly accordance with analytical solutions. Compared with conventional FDTD method, this scheme could save considerable computational resource without sacrificing solution accuracy. |
