摘　　要：分析了定向耦合器几个参数的相互关系,设计了钛扩散铌酸锂定向耦合器的仿真方案,用BPM软件对不同耦合间距的定向耦合器对工艺的容差进行了模拟计算,得到了几种耦合间距/串音变化的组合。Several parameters of the directional coupler have been analyzed. An experimentation about a Ti: LiNbO_2 directional coupler has been planned. The process tolerance for the directional coupler with different coupling distance has been simulated by using BPM software, and a family of data about the variation of crosstalk with coupling distance have been got.
