Abstract : The patent concerns an optical switch which comprises a substrate having a first refractive index and supporting electro-optic material having a second higher refractive index and defining waveguides which diverge into at least two spatially separated paths. A pair of electrodes is positioned proximate each of the spatially separated paths and when a source of electrical energy is applied to a selected pair of electrodes, an electric field is created across the associated spatially separated path which substantially lowers its refractive index and thereby diverts or switches optical energy from that path.
