OPTICAL SWITCH AND WAVELENGTH DIVISION MULTIPLEXING OPTICAL SYSTEM

摘要

The present invention discloses an optical switch and a wavelength division multiplexing optical system. The optical switch (100) includes an input port array (110), an input collimator array (120), an input micromirror array (130), an output micromirror array (140), an output collimator array (150), and an output port array (160). All input micromirrors included in the input micromirror array (130) can be deflected in two mutually perpendicular directions. Maximum movable ranges of reflected light that is output after all the input micromirrors reflect incident light with a same incident angle have no common intersection on a plane on which the output micromirror array (140) 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 (140). The optical switch and the wavelength division multiplexing optical system can implement a large-scale array and meet a requirement of a switching node for a throughput capacity.
