Abstract
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.
