Green's function approach to modelling quantum well semiconductor lasers

摘要

We summarize the recently developed approach to modelling quantum well based semiconductor lasers based on Green's functions. The derivation of quantum Boltzmann equations is outlined and Langevin approach to spontaneous emission is described. The DFB structure is discussed. The resulting small-signal equations are derived. Finally, the application to simulations of practical structure is illustrated and some numerical results are presented.
