Results of multi particle Monte Carlo studies of a mid-infrared QCL structure, for the first time fabricated by Page et al., are presented. It has been demonstrated that for the considered structure design at least 9 electron energy levels per laser segment should be used to correctly describe the electric current properties. Mechanisms responsible for electron population on higher laser level are discussed. |
