Several options are available for realizing the multi /demultiplexing function, such as the MDTFF (Multiple Dielectric Thin Film Filter), FBG (Fiber Bragg Grating) and AWG (Arrayed Waveguide Grating),etc.

• 现有的可以实现波分复用功能的器件结构有多种,如多层介质薄膜滤波器(MDTFF: Multiple Dielectric Thin Film Filter),光纤布拉格光栅(FBG: Fiber Bragg Grating),阵列波导光栅(AWG: Arrayed Waveguide Grating)等。
