ABSTRACT:
Optical switches and optical switching methods are provided. One such optical switch includes a waveguide located in a substrate that is at least partially of a non-linear optical material, the waveguide structured to receive an input optical signal, a grating located at least partially in the non-linear optical material, and a first output port optically aligned to a first radiative mode of the grating. The grating exhibits a first radiative mode corresponding to a first intensity of the input optical signal, and a second radiative mode corresponding to a second intensity of the input optical signal. The optical switch may further include a second output port optically aligned to the second radiative mode.
