| 英文摘要 | A semiconductor optical filter that includes a semiconductor substrate and a laser structure formed on the substrate. The laser structure includes an active layer of a quantum well structure and a grating formed along the active layer. The active layer is constructed to have a ground state level and an energy level other than the ground state level. A saturation gain of the ground state level is set to a value less than an internal loss, and the other energy level is set to permit an increase in the amount of carriers injected into the laser structure. The laser structure is typically a distributed feedback type laser structure. Anti-reflection coatings may be formed on the end surfaces of the laser structure. |
