Abstract

We use an effective-index self-consistent dynamical model for vertical-cavity surface-emitting lasers (VCSELs) with cylindrical symmetry to show that self-sustained pulsations can appear in VCSELs with a small radius of the current aperture and a small built-in effective-index step. The appearance of these self-sustained pulsations is due to carrier-induced antiguiding: The waveguiding is improved during the front slope of the optical pulse as a result of the carrier depletion and is worsened on the back slope of the optical pulse because of the restoration of the carrier density.
