In an optical modulation device, an inverter inverts power of a modulation signal light and generates the inverted modulation signal light. A first nonlinear medium phase-modulates a modulated light by a nonlinear optical effect of the modulation signal light. A second nonlinear medium phase-modulates the modulated light by the nonlinear optical effect of the inverted modulation signal light. An optical interference part controls interference between output light from the first nonlinear medium and that from the second nonlinear medium, and produces the phase-modulated modulated light.
