Supporting data demonstrating agile spectral multiplication of a narrowband comb in a multi-wavelength laser

Supporting data for our article entitled "Agile THz-range spectral multiplication of frequency combs using a multi-wavelength laser". Each file contain the data corresponding to a figure/panel of the article as indicated in the filename. - Fig2: we provide experimental data showing the evolution of the optical spectrum when varying the optical feedback phase. The two laser peaks being separated by 10 nm, the spectra are separated in two parts. - Fig3: we provide the data of the optical and RF spectra shown - Fig4: we provide the evolution of the high-resolution optical spectrum when varying the f_tone frequency. - Fig5: we provide the data for each of the 6 sub-panels for the two reported cases (a) and (b).
