Abstract
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 in a ⋋/4 phase shifted DFB laser id given. It is shown that spatial hole burning (SHB) results in a local gain saturation and is mainly restricted to electrons and holes within the QW.KeywordsSpontaneous EmissionQuantum WellOptical IntensityOpen ResonatorCavity AxisThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
