A quasi-3 D simulation for quantum well (QW) distributed feedback (DFB) laser diodes is presented. Longitudinal effects such as the nonuniformity of the optical intensity, local gain and spontaneous emission are considered as well as lateral effects such as current spreading and quantum carrier capture. The simulation is performed by solving several 2-D cross-sections using Minilase II and a 1-D longitudinal solver in a self-consistent fashion. As an example an analysis of spatial hole burning
