摘要:
An optical semiconductor device with a semiconductor laser formed over a semiconductor substrate, and a modulator formed over the semiconductor substrate and continuously arranged with the semiconductor laser, wherein the semiconductor laser includes a first region having a diffraction grating with a phase shift, a second region arranged between the first region and the modulator, and in which the diffraction grating is not formed, and a common active layer formed over the first region and the second region, a first electrode injecting a current into the common active layer.
