Various samples from the GaInNAs dilute nitride material system are modeled microscopically and good agreement with experiment is shown for the optical gain, linewidth enhancement factor, photomodulated reflectance and photoluminescence. Even though the differential gain is reduced by the inclusion of nitrogen, the linewidth enhancement factor is shown to stay almost unchanged. Radiative decay times are calculated and show a strong change in their density dependence above threshold.
