Abstract
An optical circuit switch includes a fiber hole array, a plurality of internal optical fibers, a collimating lens array, a MEMS mirror array, and a reflective surface. The fiber hole array includes an array of receptacles shaped to accept respective internal optical fibers. The collimating lens array is positioned adjacent to the fiber hole array. Each collimator of the collimating lens array optically couples light into or out of a corresponding one of the internal optical fibers. The fiber hole array, the collimator, the MEMS mirror array and the reflective surface are positioned relative to one another such that light exiting each of the internal optical fibers passes through its corresponding collimator and is redirected by a first mirror within the MEMS array towards the reflective surface, which directs the light back towards a second mirror of the MEMS mirror array, which in turn redirects the light towards a second internal optical fiber.
