In order to analyze the dependence of the nonlinear coefficient and dispersion property on the structural parameters of the inner air hole size and the changing of the air hole fraction, by using the full vector finite element method, the nonlinear coefficient and dispersion property as a function of frequency and design parameters were investigated. According to the analysis results, the nonlinear coefficient of photonic crystal fiber with hexagonal structure is significantly increased and the dispersion is flat. It is shown from numerical results that it is possible to design photonic crystal fiber of hexagonal structure with single mode transmission during 400nm~1160nm and high nonlinear coefficient achieves 172km-1·W-1, dispersion becomes flattened between 0.65μm~1.0μm. This result is helpful to the research of optical communication.
