The dispersion compensating property in photonic crystal fibers (PCFs) is simulated with a vectorial effective=index approach in this paper. It is found that the dispersion, dispersion slope, and Kappa parameter of PCFs can be designed neatly by changing the air hole size and the pitch in PCFs cladding. We can obtain PCFs with large absolute value of normal dispersion and negative dispersion slope at the wavelength of 1.55μm.Conventional communication nonshifted single-mode fibers (G652) and nonzero-dispersion shifted fibers (NZ-DSF,G655) can be compensated efficiently at wavelengths around 1.55μm low-loss optical communication window. It is demonstrated that there are huge potentials in designing dispersion compensating PCFs.
