Optical module and optical modulator

An optical module comprising:

• a driver that is provided on a board and generates an electrical signal according to a data signal;
• and
• an optical modulator that is connected to an optical fiber and provided on the board and that modulates light emitted from the optical fiber using the electrical signal generated by the driver, wherein
• the optical modulator is connected to the optical fiber disposed in parallel with the board;
• and
• the optical module has a cut-out portion that is formed by cutting out part of an outer shape of the optical module and that accommodates the driver so that the driver overlaps the optical fiber disposed in parallel with the board when viewed from a direction perpendicular to the board and the driver is connected to an input interface which is, on the board, formed at a position close to the optical fiber and inputs the data signal into the driver, wherein
• the optical modulator includes:
• an optical waveguide that propagates the light emitted from the optical fiber;
• a first electrode that is formed along the optical waveguide and to which an electrical signal generated by the driver is input;
• and
• a second electrode that is formed along the optical waveguide and to which another electrical signal different from the electrical signal is input, wherein
• the second electrode is formed at a location, along the optical waveguide, closer to the driver accommodated in the cut-out portion than the first electrode.
