Modeling of self-sustained pulsations in surface-emitting injection lasers

Abstract

In this paper a self-consistent dynamical model of the vertical-cavity surface-emitting lasers was developed. The model was used to investigate near-and far-field patterns and output light response on direct step bias current modulation. One- and two-mode self-sustained pulsation in VCSELs were observed. The conditions for a choice of the best fiber coupling distance were investigated.
