Optical Switch and Wavelength Division Multiplexing Optical System

摘要

An optical switch and a wavelength division multiplexing optical system are disclosed. In an embodiment an optical switch includes an input port array, an input collimator array, an input micromirror array, an output micromirror array, an output collimator array, and an output port array. All input micromirrors included in the input micromirror array can be deflected in two mutually perpendicular directions. The maximum movable ranges of reflected light that is output after all the input micromirrors reflect incident light with the same incident angle have no common intersection on a plane on which the output micromirror array is located or have a common intersection, and an area of the intersection is less than an area of a reflection region of the output micromirror array.
