ABSTRACT:
An improved optical multiplexer or demultiplexer device has a plurality of electrodes disposed on opposing surfaces of an electro-optically active plate that are resonantly excited at fundamental and harmonic frequencies for varying the effective index of refraction of the plate between the electrodes, thus coupling light successively between a first optical guide and selected ones of a plurality of optical guides.
