Abstract

This letter investigates the gain medium properties in II-VI blue-green quantum well semiconductor lasers, including band structure and carrier interaction effects. Under room temperature conditions, the many-body Coulomb interactions in the electron-hole plasma are found to be significantly more important than in infrared III-V lasers. In particular, the interband Coulombic enhancement of the optical transitions, together with a band gap renormalization result in an increase in gain and a reduction in the antiguiding or linewidth enhancement factor.
