GaInNAs laser gain

Chow, Weng W.; Jones, E.D.; Modine, N.A.; Kurtz, S.R.; Allerman, A.A.

The optical gain spectra for GaInNAs/GaAs quantum wells are computed using a microscopic laser theory. From these spectra, the peak gain and carrier radiative decay rate as functions of carrier density are determined. These dependences allow the study of the lasing threshold current density of GaInNAs/GaAs quantum well structures.
