Abstract
To provide an optical modulation element capable of suppressing electrode loss at a low frequency of 50 GHz or less, and suppressing radiation loss at a high frequency of 50 GHz or more. An optical modulation element comprises: a substrate; and at least one interaction part provided on the substrate. The interaction part includes: first and second optical waveguides formed adjacent to each other on the substrate; and first and second signal electrodes provided so as to oppose the first and second optical waveguides respectively. o ground electrode is provided in a nearby region of the interaction part, and a ground electrode is provided in the vicinity of at least one of an input part and a terminal part electrically connected to each of the first and second signal electrodes.
