Abstract
The present invention provides an optical modulator, which can be reduced in size with size reduction of an optical waveguide and electric wiring as compared to a conventional optical modulator. An optical modulator according to an embodiment includes a substrate; an optical waveguide provided on the substrate and configured to guide light; a modulation unit formed of part of the optical waveguide and configured to modulate the light; and electric wires provided on the substrate and configured to supply a high-frequency electric signal to the modulation unit. One end portion and another end portion of the optical waveguide are provided on a first end surface, one end portion of the electric wiring is provided along the first end surface, another end portion of the electric wiring is provided along a second end surface being different from the first end surface.
