阅读说明：本技术 光分插复用器及光信号处理方法 (Optical add/drop multiplexer and optical signal processing method ) 是由 米光灿 冀瑞强 李彦波 于 2018-10-10 设计创作，主要内容包括：本申请实施例提供了一种光分插复用器及光信号处理方法,涉及光通信技术领域。该光分插复用器包括：多个级联的滤波单元,每个滤波单元包括：两根端口波导,以及位于两根端口波导之间的多个微环。每根端口波导与多个微环中的一个微环耦合,每根端口波导与耦合的微环之间设置有TC,该TC用于调节端口波导与耦合的微环之间的耦合系数；每个滤波单元还包括：至少一个MEMS耦合器,每个MEMS耦合器用于调节多个微环中两个相邻的微环之间的耦合系数。每个滤波单元中的TC和MEMS耦合器用于将滤波单元的滤波谱型调节为目标滤波谱型,使得该光分插复用器能够下载/上载不同类型的滤波谱型的光信号。(The embodiment of the application provides an optical add-drop multiplexer and an optical signal processing method, and relates to the technical field of optical communication. The optical add/drop multiplexer includes: a plurality of cascaded filtering units, each filtering unit comprising: two port waveguides, and a plurality of microrings positioned between the two port waveguides. Each port waveguide is coupled with one of the micro-rings, a TC is arranged between each port waveguide and the coupled micro-ring, and the TC is used for adjusting the coupling coefficient between the port waveguide and the coupled micro-ring; each filtering unit further includes: at least one MEMS coupler, each MEMS coupler for adjusting a coupling coefficient between two adjacent microrings of the plurality of microrings. The TC and MEMS couplers in each filtering unit are used to adjust the filtering spectral pattern of the filtering unit to a target filtering spectral pattern, so that the optical add/drop multiplexer can download/upload optical signals of different types of filtering spectral patterns.)
