Master-equation theory of semiconductor lasers

Physical Review A, 1995
A master-equation approach to the semiconductor laser is derived. Projection-operator techniques are used to eliminate the fast motion occurring in the system, leading to a description of the system in terms of numbers of electrons and holes, with a fully quantum-mechanical description of the field.

Many-body theory for semiconductor microcavity lasers

Physical Review A, 1995
The influence of many-body, nonequilibrium, and cavity effects on the emission characteristics and carrier dynamics of semiconductor microcavity lasers is investigated. The nonlinear coupled equations for the carrier kinetics and the laser dynamics are derived.

Theory of a semiconductor laser

SPIE Proceedings, 1990
This paper summarizes a simple single-mode theory of a semiconductor laser and two kinds of multimode extensions. The theories are based on an quasi-equilibrium Fermi-Dirac model of a two-band semiconductor laser gain medium. We include cavity boundary conditions and find the laser single-mode steady-state oscillation intensity. The question as to when

Semiconductor laser theory with many-body effects

Physical Review A, 1989
A description of the electron-hole plasma of a semiconductor laser is developed that includes the many-body effects due to the Coulomb interactions. In particular, the plasma density-dependent band-gap renormalization, the broadening due to intraband scattering, and the Coulomb enhancement are included and evaluated for three- and two-dimensional ...
