We calculate microscopically important material properties for a GaInNAs/GaAs quantum-well laser operating in the 1.3 μm wavelength regime. The results are compared to those for an InGaAsP/InP and an InGaAlAs/InP structure with similar fundamental transition energies. The much higher confinement for carriers in the GaInNAs quantum well is shown to lead to larger material gain and differential gain and lower linewidth enhancement factors than for the later two material systems.
