仿真技术在光纤通信实验教学中的应用
通过两个例子，将Optisystem和matlab这两个软件结合进行光学仿真，两个例子分别为光波频率右移和光波幅度调制。通过这两个例子，能很好的理解这两个软件的协同仿真。上传的文件包括文献和源码，还有optisystem的osd文件，文件很全。(Two examples are used to combine the two software Optisystem and MATLAB for optical simulation. The two examples are the right shift of the light frequency and the modulation of the amplitude of the light wave. Through these two examples, we can well understand the collaborative simulation of these two software. Upload files, including documents and source code, as well as the optisystem OSD file, the document is very complete)
