摘　　要：We investigate the propagation properties of a multi-layer photonic crystal fiber with novel rhombic air holes using the finite element method,and calculate the dependence of the propagation properties on the wavelength in the fiber with different geometrical structural parameters,including the internal angle and the external arrangement of the rhombic air holes.Optimizing these parameters,we design a photonic crystal which exhibits both a small dispersion value and low loss near the wavelength of 1.55μm.
