Beam-Propagation Method (BPM) 是一种用于光子集成电路(PIC)的计算方法,它通过在2D空间中进行有限差分来计算光波的传播。这种方法可以模拟光波在介质中的传播过程,包括光与材料的相互作用以及光与光之间的干涉等现象。 在MATLAB中实现BPM的方法主要包括以下几个步骤:首先,定义光波的传播参数,包括波长、频率和电场分布...
I can propagate in space lets say gaussian beam with fft beam propagation method. How one adds time evolution of short pulse in the fft symetrized bpm ? So that the grid is 1D for x transverse coordinate, plus 1D for time, plus 1D for z propagation. Book will be helpful. 댓글 ...
This method can be used for both the guided-mode analysis and the beam-propagation analysis. To show the validity and usefulness of the present scheme, the guided-mode analysis of a rib waveguide and the beam-propagation analysis of a Y-branching polarization converter based...
1.The Results of theoretical analysis and the simulations byfinite-difference beam propagation method(FDBPM) show that the radiation losses can be less than 0.针对集成光学中普通Y分支波导分支角度小,不利于集成的问题,提出了一种新型基于渐变折射率波导的低损耗大角度Y分支结构,经过理论分析和大量的有限差分...
