| abstract | An optical semiconductor device having an optical semiconductor element in which a semiconductor laser diode and an optical modulator are integrated can be driven by a single power source. In an optical semiconductor device having an optical semiconductor element in which a semiconductor laser diode (LD) and an optical modulator (MOD) are integrated so that pn junctions are in the same direction, the semiconductor laser diode and the optical modulation The common terminal of the optical modulator is set to a reference potential (Vcm) different from the ground potential, a first potential having the same polarity as the reference potential is applied to the other terminal of the semiconductor laser diode, and the other terminal of the optical modulator is provided. Includes a circuit for supplying a second potential which is the same polarity as the ground potential or the reference potential and serves as a reference for the modulation signal. The semiconductor laser diode and the optical modulator are arranged in the reverse direction with respect to the reference potential. To drive. The reference potential is adjustable.
