Evidence of no k-selection in gain spectra of quantum-well AlGaAs laser diodes

By P.T. Landsberg, M.S. Abrahams and M. Osinski


It is suggested, contrary to present views, that the processes giving rise to radiation in undoped or lightly doped quantum well laser diodes are not subject to a k-selection rule. The reason is contained in the good fit of experimental TE gain spectra which we obtain on the basis of this assumption. This does not rule out the possibility that spectra can in principle be obtained in the future which are subject to the k-selection rule
