摘要： A 3D-MEMS optical switch, comprising: a collimator array, a PD array, a window glass which covers the PD array and is coated with a partial reflection film, a micro-electro mechanical system (MEMS) micro-mirror, and a core optical switch controller connected to the PD array and the MEMS micro-mirror. The PD array is integrated inside the core optical switch, so that the architecture and the volume of the optical switch are simplified. The window glass which covers the PD array and is coated with a partial reflection film is used to fold an optical path, and some optical signals are transmitted onto the PD array, so that the core optical switch controller adjusts the MEMS micro-mirror according to the optical power of the optical signals detected by the PD array, so as to enable the insertion loss of the 3D-MEMS optical switch to meet a preset attenuation range.

摘要： The present application discloses example optical transmission apparatuses, where one example apparatus includes a filter, a router, and an optical multiplexer. The filter is connected to the router, and the router is connected to the optical multiplexer. The filter performs parity optical demultiplexing on 2N input optical signal groups by using 2N comb filters to obtain 2N odd optical signal groups and 2N even optical signal groups, and sends the 2N odd optical signal groups and the 2N even optical signal groups to the router. The router separately routes the 2N odd optical signal groups and the 2N even optical signal groups to the optical multiplexer by using at least four AWGRs. The optical multiplexer performs, by using 2N optical multiplexers, optical multiplexing on 4N optical signal groups output by the router to obtain 2N output optical signal groups.
