| Summary: | Soliton trapping of dispersive waves during supercontinuum generation in the photonic crystal fiber with three zero-dispersion wavelengths, which is pumped by femtosecond pulses, is numerically studied. It is demonstrated that the generated supercontinuum is bounded by two branches of dispersive waves, namely, soliton-like dispersive wave and red-shifted dispersive wave (R-DW). When the R-DW with low intensity is generated in the marginal normal dispersion regime, the soliton-like dispersive wave with high intensity, which is a new frequency component, is generated in the marginal anomalous dispersion regime, whose energy mainly comes from blue-shifted dispersive wave. In addition, through the four-wave mixing effect, fundamental solitons can trap R-DW radiated from the first-ejected fundamental soliton in the normal dispersion regime, as well as soliton-like DW in the anomalous dispersion regime. These new captured components contribute to generate a wider and smoother supercontinuum spectrum. |
