Measured output spectra at various launch powers (in logarithmic scale). Output powers from the LMA35 fiber are shown in the figure.
(a)The center wavelength of the longest wavelength soliton as a function of the output powers from the LMA35 fiber. (b)Measured energies for the longest wavelength solitons at various soliton wavelengths.
Filtered soliton spectra centered at 1700 nm (a), 1870 nm (c), and 1980 nm (e) (all in logarithmic scale). The right column shows the corresponding second-order interferometric autocorrelation traces for the solitons at 1700 nm (b), 1870 nm (d), and 1980 nm (f). The pulse spectrum and the second-order interferometric autocorrelation trace of the initial input pulse are shown in (g) and (h), respectively. Note that the delay range for the input pulse (h) is 4 times larger than those for the solitons.
