ABSTRACT:
An optical waveguide apparatus comprising a substrate made of material the refractive index of which is changed by an electric effect, and an optical waveguide which is formed on a portion of the substrate and allows passage of guided light. In the apparatus, the optical waveguide includes an optical path changing section for periodically producing an electromotive force under the control of one of control light and guided light.
