| 英文摘要 | A distributed feedback semiconductor laser includes a cavity extending in a cavity-axial direction. The cavity has a plurality of regions including a first region and a second region arranged along the cavity-axial direction and capable of being independently pumped. The laser further includes a plurality of waveguides with a diffraction grating and an active layer extending along the cavity-axial direction. The waveguides are formed in the regions, respectively, and coupled to each other along the cavity-axial direction. Different first and second polatization modes are defined by the coupled waveguides. The waveguides are constructed such that light intensity distributions along the cavity-axial direction in the first and second regions when pumped are different between the first and second polarization modes. |
