The Effect of the injection current, the polarization injection and the spin relaxation time on spin lasers output

Abstract

In this paper we introduce a numerical study of the spin vertical cavity surface emitting lasers (VCSELs). the rate equations describe the spin lasers were solved numerically using Runge- Kutta method and Matlab. The effect of the injection current, the polarization injection and the spin relaxation time on the spin lasers dynamics was studied also. The obtained results show that the spin lasers output depend on the injection current and the polarization injection. The spin relaxation time enhances the laser threshold and the spin laser output.
