| 英文摘要 | In a gain-coupled distributed feedback semiconductor laser, a coating of a low reflectivity is provided on a front facet from which laser light is emitted and a coating of a high reflectivity is provided on a rear facet, thus forming asymmetric coatings. The semiconductor laser has a structure in which an absorption diffraction grating is located along an optical waveguide, and the diffraction grating includes a phase shift region. |
