All-solid photonic crystal fiber has the unique property which can used to shift the zero-dispersion wavelength down to visible light,while maintain a large mode area which is one order of magnitude larger than that may be achieved in index guiding fiber. It can be a very valuable nonlinear material in dispersion compensation and high power soliton propagation,especially for the all-fiber devices. Numerical calculation is carried out for the simulation of nonlinear evolution in all-solid photonic crystal fiber with a modified general nonlinear Schr?dinger equation. The bandgap has strong effects on the suppression of soliton selffrequency shift during the nonlinear process. The effects of peak power of femtosecond laser,the bandwidth and central wavelength of the bandgap on the nonlinear process are also analyzed.
