    • The shape of the reflectivity spectra strongly depends on the width of the different layers composing the sample. A transfer matrix approach [V. Savona, L. C. Andreani, P. Schwendimann, and A. Quattropani, Solid State Commun. 93, 733 (1995)] takes into account the precise structure of the sample and yields simulated reflectivity and absorption spectra. The exciton and trion resonances in the well are introduced by adding two frequency-dependant Lorentzian lines to the constant complex dielectric background [L. C. Andreani, G. Panzarini, A. Kavokin, and M. R. Vladimirova, Phys. Rev. B 57, 4670 (1998)]. The trion contribution to the dielectric function should not be properly Lorentzian because of the recoil of the electron [A. Esser, R. Zimmermann, and E. Runge, Phys. Status Solidi B 227, 317 (2001)] that broadens the resonance. However, this effect is masked by the inhomogenous broadening (about 1 meV) (Ref. 9) that we have added to account for the quantum well inhomogeneities [L. C. Andreani, G. Panzarini, A. V. Kavokin, and M. R. Vladimirova, Phys. Rev. B 57, 4670 (1998)].
