Current self-distribution effects in oxide-confined Vertical-Cavity Surface-Emitting Lasers

We have developed a self-consistent electro-optical model for oxide-confined vertical-cavity surface-emitting lasers, including optical polarization and spin-flip dynamics. When subjected to large signal modulation, current self-distribution effects reduce the amount of spatial-hole burning in the device, leading to a reduced overshoot during transients and to an increased damping of the relaxation oscillations.
