摘　　要：针对当前光学仿真技术的发展,为了更好的对光束在光波导器件中的实际传输过程进行仿真,从而更为准确地分析和描述光学现象及光学过程,在有限差分光束传播算法理论基础上,采用模块化方法设计光学仿真软件系统架构。系统架构主要包括布局编辑、仿真计算以及图形输出等三个模块,各个模块间通过接口进行数据处理。根据系统架构模块分析开发的光学仿真软件完成了各种光波导器件的编辑绘制、场分布计算以及波导仿真结果的图形可视化输出,并通过仿真实例的仿真过程及结果的数据对比分析验证了该软件系统设计对光束传播过程仿真的有效性,以及在集成光学研究中的实用价值。According to the development of current optical simulation technology, in order to simulate the course of beam propagation in the optical waveguides in practice better for accurately analyzing and describing optical phenomenon, and based on the basic theory of Finite - difference beam propagation method （ FD - BPM ） and method of simulating mode calculation, the methods of modules are used to design a systematic architecture of optical simulation software. The architecture is made up by three modules, namely the module of editing, module of calculation and module of graphic displaying, and the data can be processed by the interfaces among these modules. With analysis of modules in the systematic architecture, various types of waveguides can be plotted, while the field distribution caleulation and graphics visualization displaying of waveguides simulating results can be finished by the simulation software. And finally a simulation course of an example and the comparison of the results prove the validity of this software system and its application value in the optical research.
