Abstract
An optical device includes a waveguide in which light is guided and that has electro-optical effect and thermo-optical effect, and a heater electrode that is arranged on one of side surfaces of the waveguide and that heats the waveguide. The optical device includes a parallel electrode that is arranged on the other of the side surfaces of the waveguide, that is electrically connected to the heater electrode, and that has high resistance as compared with the heater electrode.
