| 英文摘要 | A distributed feedback semiconductor laser includes a cavity extending in a cavity-axial direction and including a plurality of regions, and 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, coupled to each other along the cavity-axial direction, and define different first and second polarization modes. The semiconductor laser further includes a light intensity distribution control portion formed in the cavity and having a function to relatively and locally strengthen light intensity distributions for the first and second polarization modes in the cavity-axial direction with a polarization dependency, and a control unit for independently stimulating at least two of the regions. |
