1. An optical switch comprising:

  • a substrate;

    a first buried optical waveguide for propagating an optical signal, where said optical signal propagates in the first optical waveguide along a first direction;

    a second buried optical waveguide extending in a second direction different than the first direction; and

    a diffractive optical element disposed above a total internal reflection region of the substrate and moveable relative thereto between a switching position wherein the optical signal is switched from the first optical waveguide into the second optical waveguide and a non-switching position wherein the optical signal reflects at the total internal reflection region under total internal reflection.
