In this paper,numerically simulate that high-order soliton pump-pulse at wavelength anomalous dispersion district and the signal pulse wavelength in the normal dispersion,through cross-phase modulation effects,under Raman scattering effects,produce compression pulse pair in photonic crystal fibers.First,we discussed under the influence of the higher-order dispersion,femtosecond pulse based on cross-phase modulation,produced pulse pair no longer maintain symmetry,but generated a blue shift.In addition,considering the impact of high-order nonlinear effect,femtosecond pulse signal from the normal frequency dispersion district moved to the anomalous dispersion district,the generated pulse evolved from two to one,is greatly impacted by Raman redshift,at the same time,the peak power pulses significantly increase.
