Beyond Quasiequilibrium Theory

  • Weng W. Chow
  • Stephan W. Koch
  • Murray SargentIII


In this final chapter we discuss results for semiconductor lasers and amplifiers that go beyond the quasiequilibrium assumption made in the previous chapters. First, in Sec. 11-1 we outline a microscopic theory for semiconductor lasers that treats both the light field and the carrier system quantum mechanically. This approach applies nonequilibrium quantum mechanical (Green’s function) techniques to derive a set of coupled equations for the light field and carrier distribution functions. It allows us to analyze the stationary and dynamical responses of the interacting photon and electron-hole systems in semiconductor lasers and amplifiers including many-body effects of the electron-hole plasma and the photon system.
