ABSTRACT:
Light propagating in a waveguide is modulated by deforming a cladding on at least one surface of the waveguide. The cladding has a thickness at least equal to the exponential depth of the evanescant field of the propagating light. A pair of electrode means is used to impress a field across the waveguide and cladding so that the cladding is deformed to a degree sufficient to interfere with the evanescant field and to modulate the propagating light.
