Properties of nonlinear microstructured fiber fabricated in our laboratory are theoretically analyzed using the finite element method. This fiber has a high nonlinearity and phase matching for the dispersion wave generation. To achieve all-fiber nonlinearity in microstructured fiber, the dependence of dispersion wave on the pump power is investigated. When changing the pump power at 1032 nm with a femtosecond fiber laser, the near-infrared dispersion waves cover a region from 753 to 789 nm. The central wavelength and bandwidths alter obviously, and the fiber length has a remarkable impact on pulse broadening and frequency spectrum. Results coincide with the analyses. These results could be a reference for all-fiber nonlinearity of microstructured fiber, and lay a foundation for biological and medical applications, especially some researches on the near-infrared source for nonlinear light microscopy.
