Optical module and optical modulator

An optical module in which a reception optical fiber configured to input an optical signal from an outside and a transmission optical fiber configured to output an optical signal to the outside are connected to one end, and a receiver configured to receive an electric signal used for modulating light in the optical modulator is provided at another end opposite to the one end, comprising:

• an optical modulator including:
• an optical modulator chip having an optical waveguide having a light input end portion to which light from a light source is input, a light output end portion which outputs light to the transmission optical fiber, and a bent waveguide portion which is bent between the light input end portion and the light output end portion, a bias electrode to which a bias voltage is applied, the bias electrode being provided between the light input end portion and the bent waveguide portion along the optical waveguide, and a signal electrode to which the electric signal is input, the signal electrode being provided between the bent waveguide portion and the light output end portion along the optical waveguide;
• a bias input terminal electrically connected to the bias electrode and configured to input a bias voltage to the optical modulator;
• and
• a signal input terminal configured to input the electric signal to the optical modulator, the signal input terminal being provided closer to the other end than the bias input terminal and electrically connected to the signal electrode.
