摘　　要：利用综合光学设计软件ZEMAX对激光点火用微光开关进行了光学建模和耦合特性的仿真分析.对两根光纤的纵向距离、横向偏移和角度倾斜三个耦合效率的影响因子进行了仿真分析.得到的结论是:纵向距离对耦合效率的影响不大,横向偏移和角度偏移对耦合效率的影响较大.根据仿真分析结果,明确了光纤连接型微光开关可靠保险和解保要达到的工艺技术指标.The optical modeling and simulation of micro optical switch using in laser ignition are made by ZEMAX. Three key coupling factors, longitudinal,transverse and angular misalignments between two op- tical fibers are analyzed. The conclusion is shown that the effects of transverse and angular misalignments on the splice loss are more significant than longitudinal misalignment. The processing technical guidelines that assuring acceptable ＂safety＂ and ＂arming＂ of micro optical switch are made according to the results of analysis.
