OPTICAL MODULATION ELEMENT

Abstract: an optical modulation element includes a substrate; first and second waveguides formed of an optical material film having a ridge part which are disposed on the substrate and provided parallel to each other; a buffer layer disposed on the first and second waveguides; and first and second signal electrodes provided along the first and second waveguides. the first and second signal electrodes each include a solid-line part provided outside the respective first and second waveguides in a plan view and provided continuously in the traveling direction, a dashed-line part provided so as to overlap the respective first and second waveguides in a plan view and provided intermittently in the traveling direction, and a connection part connecting the solid-line part and dashed-line part. a width wof the dashed-line part is larger than a width wof the ridge part.
