ABSTRACT:
A semiconductor optical amplifier device has an amplification factor that does not vary even if an injection current thereinto is changed. The semiconductor amplifier device includes a laser structure and an active region formed in the laser structure along a waveguide thereof. The active region is constructed so that a carrier density distribution and a light distribution in the active region cooperate to keep a resonator length of the laser structure unchanged irrespective of the change in the injection current into the laser structure.
