Figure 6

Evolutions of the Gaussian input pulses along the taper modeled by the GNLSE. The evolutions of the waveforms in the top row are obtained in (a) NIWs at 1550 nm, (b) DDWs at 1550 nm, (c) NIWs at 2150 nm and (d) DDWs at 2150 nm. The evolutions of the spectra in the bottom row are obtained in (e) NIWs at 1550 nm, (f) DDWs at 1550 nm, (g) NIWs at 2150 nm and (h) DDWs at 2150 nm.
