ABSTRACT:
An optical switching device comprises an optical waveguide formed from two light-transmitting materials having an interface between them, and in which the refractive index of one of the materials can be altered by an external influence; the other has a light path directed at the interface at an angle such that by varying the refractive index of the first material the light can either pass through the material or be reflected at the interface. By utilizing a plurality of such interfaces in sequence the light may be selectively switched along several different paths.
