Abstract

Results of investigations on the dependence of the gain spectra, their polarization properties, and their peak emission values, on both the quantum well width and injection current are presented for single mode GaAs/AlGaAs graded-index separate confinement heterostructure single quantum well (GRINSCH SQW) lasers. Further, the relationships between the laser parameters critical to lasing with the n = 1 subband transitions are analyzed in terms of the material optical gain of the quantum well.
