Abstract

The role of many-body Coulomb interactions in the electron-hole plasma of II-VI quantum well lasers was investigated. A microscopic theory based on the semiconductor-Bloch equations in the screened Hartree-Fock approximation was applied. It was determined that many-body effects, in the form of band gap renormalization and Coulomb enhancement, had significant influences on the gain and carrier-induced refractive index. They were especially relevant in determining carrier density dependencies. Although a specific ZnCdSe-ZeSe structure was treated in this work, the results applied to II-VI lasers in general.
