Claim Text:
1. A 3-dimensions micro-electro-mechanic system 3D-MEMS optical switch, comprising: a collimator array, a power detector (PD) array, window glass covering the PD array and partially plated with a reflective film, a micro-electro-mechanic system MEMS micromirror, and a core optical switch controller connected to the PD array and the MEMS micromirror; wherein the window glass covering the PD array and partially plated with the reflective film is configured to acquire an optical signal from the collimator array, partially reflect the optical signal acquired from the collimator array onto the MEMS micromirror and partially transmit the optical signal acquired from the collimator array onto the PD array, and is further configured to acquire an optical signal reflected by the MEMS micromirror, partially reflect the optical signal reflected by the MEMS micromirror onto the collimator array and partially transmit the optical signal reflected by the MEMS micromirror onto the PD array; the PD array is configured to detect an optical power of the optical signal transmitted onto the PD array; and the core optical switch controller is configured to adjust the MEMS micromirror based on the detected optical power of the optical signal transmitted onto the PD array, to make insertion loss of the 3D-MEMS optical switch meet a preset target attenuation value.
