| 英文摘要 | An optical semiconductor device includes a semiconductor laser, a first optical waveguide, an optical coupler for branching light guided from the semiconductor laser through the first optical waveguide into two lights, two second optical waveguides, diffraction gratings provided individually on the two second optical waveguides, and an optical detector for detecting light guided through one of the two diffraction gratings, and the components are provided on the same substrate. The optical semiconductor device is configured such that reflection returning lights from the diffraction gratings side to the semiconductor laser side interfere with each other and thereby extinguish each other at the optical coupler and the phases of the reflection returning lights from the diffraction gratings side are displaced from each other by π at the optical coupler portion. |
