Paper Abstract

In this paper, a quasi-three-dimension theoretical model for the Vertical-Cavity Surface-Emitting Laser with oxide-confined layers is showed. The distributions of the equal-potential line, injected current density, carrier concentration and the optical field distribution in the cavity are calculated self-consistently by the finite difference method. The influences of the light output window's radius and oxide-confined layers window's radius are studied. At the same time, we study the influence of the N-type DBR on some characteristics of the VCSEL. The results show that there would be a large difference with practical VCSEL ifthe N-type DBR layers were neglected.
