• This study proposes a novel structure of index-guiding square photonic crystal fibers (SPCF) having simultaneously ultra-flattened chromatic dispersion characteristics and low confinement losses in a wide wavelength range. The finite difference method (FDM) with anisotropic perfectly matched layers (PMLs) is used to analyze the various properties of square PCF. The findings reveal that it is possible to design five-ring PCFs with a flattened negative chromatic dispersion of 0-1.5ps/(nm.km) in a wavelength range of 1.27μm to 1.7μm and a flattened chromatic dispersion of 0±1.15ps/(nm.km) in a wavelength range of 1.25μm to 1.61μm. Simultaneously it also exhibited that the confinement losses are less than 10^<-9>dB/m and 10^<-10>dB/m in the wavelength range of 1.25μm to 1.7μm.
