We design a hexagonal model of dispersion compensating photonic crystal fiber using finite element method with perfectly matched layer as an analysis tool. In this case, we change different parameters-diameter of air holes and pitch to observe the effects of different properties of dispersion compensating photonic crystal fiber such as effective area, confinement loss and chromatic dispersion. We have achieved large negative chromatic dispersion, and low confinement loss. Moreover, numerical results show that small length of the proposed dispersion compensating photonic crystal fiber is achieved. The proposed microstructure fiber can be used for wide band high speed optical transmission systems.
