Fig. 6From: From spectral broadening to recompression: dynamics of incoherent optical waves propagating in the fiberExperimental spectral evolutions of double-peak spectra. A Output spectra in logarithmic scale at 3 different positions: input, 3 and 35 km. It’s worth noting that the spectral FWHM linewidth broadens to its maximum with 3-km propagation. B Output spectra in linear scale. C Spectral broadening factors dependence on the propagation distance. Scatters: experimental data; lines: spline fittingBack to article page
