Abstract

Firstly, the possibility of yielding soliton self-trapping in the photonic crystal fiber (PCF) is analyzed, and it is found that, due to the high modal birefringence of PCF, the femtosecond-order initial pulse must be considered in order to realize the soliton self-trapping, so the effects of higher-order nonlinearity and higher-order dispersion need to be taken into account. Secondly, based on the coupled nonlinear Schrodinger equations, the influences of higher-order nonlinear and dispersive effects on the threshold value and the quality of soliton self-trapping are studied in detail with the slip-step Fourier method. The numerical results show that, the higher-order nonlinearity doesn't affect the threshold value but induces both the attenuation and red shift of the two polarized components, and the higher-order dispersion not only influence the pulse shape and width of two polarized components, but also change the threshold value under appropriate conditions. In conclusion, the PCF can also yield the soliton self-trapping with the interactions of all effects above.
