Abstract
A four-part electro-optical switch for switching optical radiation from one aveguide to another. Parallel waveguides are embedded in the surface of a substrate and provided with separating ends for transmitting radiation through the waveguides. Curved electrodes on the outer side of each waveguide in cooperation with a central electrode and separate voltage sources change the electro-optic properties of the waveguide such that radiation may be switched from one waveguide to the other when the voltage source is in the 'on' state.
