| 摘 要： | 理论分析和设计了一种用于850和1550nm两个光通信窗口的、集波长信号分离和光开关功能于一体的智能集成分波光开关，并将弧形结构全内反射面用于该集成结构中. 基于Si基半导体SiGe合金材料的等离子体色散效应，对该结构智能集成分波光开关的串音、损耗、消光比等特性进行了分析和模拟计算. 计算得到，作为光开关时器件的平均串音、插入损耗和消光比分别为-19, 1.3和21dB，作为分波器时平均串音和插入损耗分别为-11和1.1dB. 设计结果表明，该集成器件不仅能够实现850和1550nm两种波长光信号的开关，而且还能对这两种波长的光信号进行分离，是一种有前途的智能化集成分波光开关.
