Abstract
An optical modulator having an optical modulation part and a connection part for an optical fiber propagating light. The optical modulation part has a modulation substrate of an electro-optic material, a modulation optical waveguide formed on the modulation substrate, a high frequency interaction part for applying a voltage to the modulation optical waveguide to modulate the propagation of light, a first supporting substrate and a first adhesion layer for adhering the modulation substrate to the first supporting substrate. The connection part has a connection substrate of an electro-optic material, a connection optical waveguide formed on the connection substrate, a second supporting substrate, and a second adhesion layer for adhering the connection substrate to the second supporting substrate. The modulation substrate is adhered to the connection substrate. The first supporting substrate is adhered to the second supporting substrate. The modulation optical waveguide is connected to the connection optical waveguide.
