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.
