Abstract
An optical switch array comprises a plurality of optical switches of the kind utilizing the interaction between light propagating along one of two waveguide path sections in close proximity to one another and an electrical field produced by electric switching voltages applied between electrodes actively associated with the waveguide path sections in order to effect switching of the light from one of the waveguide path sections to the other. The waveguide path sections which provide links between the optical switches of the array and which require electrical isolation from one another have dissimilar physical or other characteristics in order to prevent coupling therebetween in the presence of a nearby electric field.
