ABSTRACT:
An improved device of the type suitable for coupling light waves from a first waveguide into a second waveguide, both waveguides being arranged by an integrated technique on a given substrate in intersecting fashion one above the other. Insulated electrodes adjacent opposed faces of the waveguides at the intersection zone between the waveguides permit generation of an electric field in response to an applied voltage therebetween. By forming the waveguides of electro optical material having appropriate indices of refraction, coupling is achievable between first and second waveguides.
