摘要：
An optical semiconductor device includes an element in which a laser diode and an optical modulator are integrated, and a circuit that sets a common node of the laser diode and the optical modulator at a reference potential different from a ground potential and drives the laser diode and the optical modulator in opposite directions with respect to the reference potential.
