20. -2) indicates the presence of nonradiative decay processes, increasing as the pump energy is increased. The resulting gain saturation has been mainly attributed to nonlinear effects, like bimolecular exciton annihilation, induced by the high density of excitons formed at very intense photon fluxes. This behavior is confirmed by a square-root dependence of the high-power emission on excitation density, consistent with the bimolecular annihilation model (dotted fitting curve in Fig. 3).
21. The ASE peak position depends on both the maximum gain energy and on the maximum transmission energy of the waveguides, depending on the film thickness.

26. We obtained such information from the spectral mode spacing of the modulated PL recorded when pumping below threshold and from the FWHM of the laser line (Fig. 5), respectively.
