摘要：随着光电子集成和各种平面波导器件的集成度、复杂度越来越高以及光器件的结构越来越精密，用解析的方法对器件进行分析和设计已经无法实现。为实现光学器件的良好设计，以有限差分光束传播法（FDBPM）为仿真算法开发了光学芯片仿真软件，实现了光波导器件的模拟仿真。由该仿真结果与Matlab仿真结果的对比可知，该仿真软件能达到显示波导状态的基本要求。

Abstract: As the integrity and the complexity of the optical electronic and optical devices are more strictly demanded, and the structure of the optical devices is more precise, the analysis and design of optical devices is unable to realize, using analytic methods. Aiming at realizing the good design of optical devices, the software based on finitedifference beam propagation(FDBPM) was developed for the simulation of the optical waveguide and the simulation of optical waveguide devices was realized. Compared with the result of the Matlab, the result of the software is able to show the state of the waveguide.
Key words: finite-difference beam propagation method(FD-BPM); optical simulation; refractive index
