Abstract
An optical switch includes one or more multi-core fibers, a lens, a liquid crystal polarization grating, and a MEMS tilt mirror array. In the MEMS tilt mirror array, each of multiple MEMS tilt mirrors is configured to switch a propagation path of an input light from a corresponding core so as to reflect the input light from the corresponding core at a tilt angle controlled by a controller and propagates a corresponding reflected light to a core selected by the controller. The liquid crystal polarization grating is arranged so that the input light from a core corresponding to each of the multiple MEMS tilt mirrors passes through the liquid crystal polarization grating and is incident on a corresponding MEMS tilt mirror as a zeroth order diffracted light.
