Abstract
A many-body theory for the electron-hole plasma in a semiconductor laser has been developed for 3-D bulk semiconductors and quasi-2-D quantum well structures. Starting from the generalized semiconductor Bloch equations and using a Pade approximation for the optical susceptibility, gain/absorption and refractive index spectra that clearly show the effects of Coulomb enhancement, bandgap renormalization, broadening, and plasma screening have been computed. The gain/absorption spectra for bulk and quantum well GaAs at different temperatures are shown and discussed. The influence of the Coulomb enhancement is especially pronounced in the low-temperature results.
