该文档描述如何用FRED仿真使用球形透镜的光纤耦合,另外,使耦合光纤在纵轴和横轴上扰动,利用FRED脚本语言进行相应的容差分析,仿真结果直接通过COM在Excel 里记录和绘图。要介绍的这个仿真程序源于Cheung和Yiu的论文:Cheung, Y.M. and Yiu, C.H. “Simulation of the Alignment Sensitivity on the Coupling Efficiency of a Ball-Lens Capped TO-Can Laser Diode Source into a Single Mode Fiber”. Int’l Symposium on Electronic Materials and Packaging. 2002; 197 – 203.
