【摘要】 在微光电子机械系统(Micro-Optic-Electro-Mechanical System,MOEMS)理论的基础上,设计了应用于光波导加速度系统的双Y分支1×4耦合器。对微光机械系统做了简要介绍,对所设计的系统耦合器进行了理论研究和计算,并对系统进行了结构优化,采用S型反正弦波导连接两平行直波导的弯曲波导。设计的耦合器长度为20.4 mm,具有结构紧凑、损耗低、不易受外部温度影响等特点。更多还原

【Abstract】 Based on the principle of MUEMS,double Y-branch waveguide 1×4 couplers used lor optical waveguide accelerometer system were designed.The MOEMS was introduced briefly.Through theoretical research,calculation of the couplers and the use of arcsine type,the length of 1×4 couplers were found only 20.4 mm.So there are many unique properties using double Y-branch waveguide couplers in this system,such as compact size,low loss and guarded against the impact of the outside temperature.更多还原
