简要分析了列阵波导光栅复用器／解复用器的传播特性，利用有效折射率法求解了ＳｉＯ２：ＧｅＯ２单模脊型掩埋通道波导的传播常数，并在此基础上完成了４×４列阵波导光栅复用器／解复用器的理论设计和数值模拟分析，这些结果对设计实用化器件有较大帮助。
The propagation characteristics of the arrayed waveguide grating multiplexer / demultiplexer are briefly analyzed. The propagation constant of the SiO2: GeO2 single mode ridge buried channel waveguide is solved by the effective refractive index method. Based on this, the 4 × 4 Array waveguide grating multiplexer / demultiplexer theoretical design and numerical simulation analysis, these results on the design of practical devices have a greater help.
