Is it possible to combine transport models with laser emission?nTWLM combines transport model (diffusion and carrier recombination) with laser emission. It is a 1D model suitable for edge emitting lasers and can be used for a standalone physical simulation or in a circuit simulation (combined with various external cavities):nhttps://support.lumerical.com/hc/en-us/articles/360036108274-Laser-TW-TWLM-INTERCONNECT-ElementnWe do have another solver called CHARGE, which is a 2D/3D finite element drift diffusion solver with standard mobility and tunneling models. While CHARGE does not model laser emission physically, it does have a stimulated recombination model and the parameters of this model can be populated from the TWLM simulation. Find more details about the model in section Stimulated recombination here:nhttps://support.lumerical.com/hc/en-us/articles/360034919113-Semiconductor-material-model-propertiesnQuestion migrated from the Lumerical Knowledge Exchangen
