Two different structures of waveguide interference filters are investigated and the output spectrum of a two-cavity structure with 27 periodic layers and the field distributions of a single-cavity structure are calculated.

• 根据这种方法优化设计了两种波导干涉滤波器单元器件,并且以27层开放式波导干涉滤波器双腔结构为例,计算了垂直入射时的输出光谱和单腔结构滤波后的场强分布。
