摘　　要：提出一种新型的基于压电陶瓷以及微流控技术的阵列光开关,重点研究了该光开关波导层的光功率损耗。运用Opti-FIBER软件对波导层波导的耦合损耗进行了分析与仿真,实验测量了不同情况下光开关的耦合损耗。仿真及实验研究表明,该光开关理论最低插入损耗值为0.042 524 dB,光开关速度为100μs。该光开关具有结构简单、开关速度快和损耗低等优点。This paper introduces a novel array optical switch based on piezoelectric ceramics and the micro-fluidic control technology,with a focus on the optical power loss of its waveguide layer.It analyzes and simulates the coupling loss of the waveguide layer using Opti-FIBER and experimentally measures the coupling losses in different conditions.The results show that this switch has such advantages as simple structure,fast response,100 μs,and low loss,minimum theoretic insertion loss 0.042 524 dB.
