Comprehensive simulation of vertical cavity surface emitting lasers

The performance of today´s commercial vertical cavity surface emitting lasers (VCSELs), results from designs that include the sensitive interplay of thermal, electrical and optical effects. Simulation with a predictive character needs to capture these aspects quantitatively, and the underlying equations have to be solved in multiple dimensions in space. In this paper, the current status of LASER-DESSIS is presented including an improved many-body gain model, and a detailed comparison to measurements evaluates the predictive potential.
