英文摘要PURPOSE:To strength the selectivity for TE polarization without causing the increase threshold value current by using a super grating structure for an active layer, in a semiconductor laser wherein a diffraction grating of strong wavelength selectivity is integrated to a laser wave guide. CONSTITUTION:A DBR laser is formed of an N-GaAs substrate 1, an N-clad layer 2, an active layer 11, a P-clad layer 3, P-contact layer 4, Bragg reflection type (DBR) reflection parts 8 and 9, and electrodes 6 and 7. Here, the active layer 11 is composed of a GaAs/Al GaAs super grating layer, and has the super grating structure wherein a GaAs well layer and an AlXGa1-XAs barrier layer are alternately stacked to a multilayer. Thereby, the selectivity for TE polarization is strengthened by a difference of large gains of TE polarization and TM polarization due to the super grating structure, without damaging of a characteristic of excellence in the singleness of the vertical mode which the DBR laser has, and of excellence in the temperature stability of the laser oscillation wavelength; therefore a deflection surface can be stabilized.
