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.

Abstract
An optical modulator, methods of manufacturing and operating the same, and an optical apparatus including the optical modulator are disclosed. The optical modulator includes an electro-optical converter and an optical-electric converter, stacked perpendicular to a substrate, and a gate transistor. The gate transistor 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 while bypassing the electro-optical converter when gating ON is performed.
