ABSTRACT:
An electrooptic switch in which one of four channel waveguides is selectively induced in a thin slab of electrooptic material by the application of an electric field between intersecting strips of electrodes disposed adjacent the top surface of the slab and other intersecting strips of electrodes disposed adjacent the bottom surface directly below the top surface strips. The electrode strips comprise (1) primary electrodes to which constant potentials are applied to induce optical paths partially through the slab and (2) switching electrodes, vertically displaced and electrically isolated from the primary electrodes, to which alternating potentials are applied to complete the desired optical path through the slab.
