Abstract

Optical gain and spontaneous emission spectra are calculated for CdZnSe/ZnSSe single quantum well (QW) structures at room temperature with various many-body effects taken into account. It is found that Coulomb enhancement has a large effect on the gain-current relation derived from these spectra. When Coulomb enhancement is ignored, values of threshold current at various cavity lengths are overestimated by about 40 to 50% compared with the measured threshold currents. Good agreement with experiment is reached when Coulomb enhancement is included in the calculation.
