We propose and demonstrate a bidirectional optical add-drop multiplexer for use in single-fiber bidirectional networks. With effective use of multiport circulators, fiber-Bragg gratings, and a single amplifier element, the new structure can add and/or drop channels in both directions and achieves more than 16 dB of bidirectional gain. The device utilizes Bragg gratings and light absorber to remove Rayleigh backscattered and reflected light at the input stage.
我们提出并演示了一种用于单光纤双向网络的双向光分插复用器。通过有效利用多端口环行器、光纤布拉格光栅和单个放大器元件，这种新结构能够在两个方向上添加和/或下路通道，并实现超过16 dB的双向增益。该器件利用布拉格光栅和光吸收器在输入阶段消除瑞利背向散射光和反射光。
