A kind of zero dispersion and high nonlinearity photonic crystal fiber at the wavelength of 1 μm is designed. Characteristics such as dispersion, effective mode area, and nonlinear coefficient of the fiber are investigated by the finite element method. Simulation results show that the dispersion is 0 at the wavelength of 1 μm when the air hole pitch is 4.344 μm, the effective mode area is 11.07 μm<sup>2</sup> and the nonlinear coefficient is 18.17 W<sup>？1</sup>？km<sup>？1</sup>. It could be widely used in the high speed optical communications, optic fiber sensors and nonlinear optics.</span><span style=\"line-height:1.5;\"></span>
