This paper presents results of numerical simulations of a nitride semiconductor vertical-cavity surface-emitting laser (VCSEL) with a tunnel junction. The modeled laser is based on a structure created at the University of California in Santa Barbara. The analysis concerns the impact of the position of laser’s active area on the emitted power. Both small detunings from the standing wave anti-node, and positioning of the active area at different anti-nodes are considered.
