ABSTRACT:
An optical modulator includes a substrate having an electrooptic effect, an optical waveguide formed on a surface of the substrate, and a control electrode formed on the substrate, and a control electrode formed on the substrate to oppose the optical waveguide. In this optical modulator, the control electrode is formed by stacking a plurality of layers in a direction perpendicular to the substrate surface.
