ABSTRACT:
Various embodiments of the present invention are related to photonic systems and methods that can be used to encode data in carrier electromagnetic waves. In one embodiment of the present invention, a photonic switch comprises: a waveguide configured to guide electromagnetic waves; a number of holes in the waveguide that prevent propagation of the electromagnetic waves beyond the holes; a reservoir located beneath the holes and filled with a liquid having the same refractive index as the photonic crystal; and a device for forcing the liquid into the holes so that the refractive index of the holes matches approximately the refractive index of the waveguide and the electromagnetic waves can propagate within the waveguide beyond the holes.
