Since the lasing operation of vertical-cavity surface-emitting lasers results from the interaction of electrical carrier transport, optical and thermal effects, a realistic model should include each of them and their interplay. Aiming to such an achievement, this paper presents our in-house Vcsel Electro-opto-thermal Numerical Simulator VENUS, consisting of the 3D vectorial optical code VELM, a model for the quantum well optical response, a heat equation solver and a quantum-corrected drift-diffusion simulator. Each of these components and their coupling strategy is described, and the resulting model is validated through the comparison with experimental results.

Abstract
Since the lasing operation of vertical-cavity surface-emitting lasers results from the interaction of electrical carrier transport, optical and thermal effects, a realistic model should include each of them and their interplay. Aiming to such an achievement, this paper presents our in-house Vcsel Electro-opto-thermal Numerical Simulator VENUS, consisting of the 3D vectorial optical code VELM, a model for the quantum well optical response, a heat equation solver and a quantum-corrected drift-diffusion simulator. Each of these components and their coupling strategy is described, and the resulting model is validated through the comparison with experimental results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
