Abstract

An excited semiconductor is described by nonlinear equilibrium Green's functions for the interacting quasi-particles namely: carriers; photons; and plasmons. Coupled band structure and quantum confinement effects are included in the carrier propagators, and in the transition matrix elements, which gives rise to optical selection rules. Correct gain lineshapes are obtained in a simple way by avoiding the Kubo-Martin-Schwinger (KMS) condition. The major contribution that gives rise to excitonic spectra is due to the transition matrix in the polarization function.
