Résumé:
We present nonlinear optical spectroscopy in GaN/AlN quantum dots that allow for the measurements of the homogeneous broadening of the intraband transition at 1.55 µm. We find that the population relaxation is driven by Auger processes, which play on the contrary a minor role in the decoherence dynamics.
