Figure 2 (Fig2a, Fig2b, Fig2c, and Fig2d) presents the results of numerical simulation of the spectral compression at 1730 nm pulse propagation in 822 m of CPF (comb-profile fiber). The results include optical spectra (a) and temporal profiles (b) of the input and output pulses, a dispersion profile of the CPF and the evolution of the spectral FWHM across the CPF length (c), and a soliton order, N and the pulse temporal width as a function of the fiber length (d).
Figure 4 (Fig4a and Fig4b) presents the optical spectra of the tunable solitons before spectral compression and the optical power stored in solitons at wavelengths between 1.79 and 1.92 μm (a), and the optical spectra of the tunable solitons after spectral compression (b).
Figure 5 presents the comparison of the numerical and experimental results of spectral compression for three different compressed solitons at 1682, 1730, and 1839 nm.
Figure 6 (Fig6a and Fig6b) presents the optical spectra of the tunable and compressed solitons before and after amplification (a), and the output power levels as a function of the wavelength for compressed solitons after amplification (b).
