Example of simulation of the optical reflectivity spectra of PSi samples. The experimental data are those shown in Figure 8. The curves in (a) are the experimental (solid red line) and simulated (dashed blue line) reflectivity before the Er doping. The curves in (b) are the experimental (solid green line) and simulated (dashed black line) reflectivity after the Er doping. The good agreement of the experimental data and their simulation in the whole spectral range considered ensures the reliability of the fitting results.
