The photonic crystal fibres (PCF) are more better than conventional optical fiber. In this paper we proposed a new design of photonic crystal fiber using borosilicate material. Triangular lattice is used with linear and elliptical waveguide in cladding. The PCF are very useful for optical transmission. For better transmission, ultra flattened dispersion or near to zero dispersion is desirable. Finite Difference Time Domain (FDTD) method and transparent boundary condition (TBC) is used to evaluate the dispersion property in a high-index core PCF. Through reproduction and optimizing the PCF, we find that the projected photonic crystal fibres give flattened dispersion in wavelength range of 0.5μm to 2.0 μm. This method produced best result at third attenuation coordinate (1.55μm) over 1.4 μm to 1.8 μm wavelength range and found the dispersion and ultra flattened that has better performance than conventional photonic crystal. PCF can be used as a dispersion compensating fiber in optical window with high potential.
