1. An optical modulator comprising:

  • an electro-optical converter and an optical-electric converter, which are stacked in the direction perpendicular to a substrate; and

    a gate transistor which, when gating ON is performed, gates a signal transmitted to the electro-optical converter from the optical-electric converter and allows charges generated in the optical-electric converter and charges remaining in the electro-optical converter to flow through the gate transistor while bypassing the electro-optical converter.
