Summary:(1) Field of the Invention A waveguide optical switch has a waveguide whose refractive index changes can be controlled by an electro-optic effect and an UV guide waveguide for coupling an ultraviolet radiation to the waveguide. A portion of the waveguide and a portion of the UV guide waveguide make up a directional coupler.
