Stimulated emission from a (CdMg)Te separate confinement quantum well laser

Abstract

In this article lasing action of (CdMg)Te quantum well laser structures is reported. The separate confinement quantum well laser structures were grown by molecular beam epitaxy. Stimulated emission has been observed at 77 K and at room temperature. The structures emitted at wavelengths of around 650 nm at room temperature. A (CdMg)Te/CdTe superlattice has been used for the active layer as well as for the electrical confinement layer. Due to this an efficient radiative recombination even at room temperature could be obtained. The distribution of the intensity of the light across the waveguide has been calculated.
