Real three-dimensional spatio-temporal VCSEL simulation

We present a real three-dimensional (3D) dynamically combined model for the first time, realized with finite volume method on a flexible, triangle-based mesh. The simulation consists of a current flow, a heat flow and optical mode solvers, coupled to each other self-consistently in the quantum well laser dynamics. The transport of free carriers across the mirrors satisfies the Laplace-equation, where heterojunctions are modeled with increased resistivity in the axial direction.
