Abstract

Measurements and microscopic calculations of the α-factor in (GaIn)(NAs) quantum well lasers were discussed. Data was obtained from the shift of the Fabry-Perot modes with injection current was used to eliminate temperature-dependent artifacts. The molecular beam epitaxy was grown 350 μm long ridge-waveguide laser structure for the experiment. It was found that the value of α at the laser emission wavelength in this structure is around 2.5 +/-0.4 and remains constant with carrier density variations for a fixed emission wavelength.
