Dispersion is one of the most significant parameters of photonic crystal fibers. The dispersion properties of total internal reflection photonic crystal fibers are numerically studied using the simple empirical relation method and CUDOS simulation software, which is based on the multipole method, by analyzing various numerical methods available currently. And the effects of air hole diameter d, hole pitch Λ, and d/Λ on the dispersion properties are numerically investigated in details, and some results, which are useful for design of photonic crystal fibers, are given. A photonic crystal fiber, whose length is 328 mm, hole diameter is 2.17 μm, and hole pitch is 3.47 μm, is tested using the ultro-broadband and high precision dispersion measurement system constructed previously, which is based on white light interferometer using supercontinuum as the light source. The experimental dispersion curve is well in agreement with the numerical results, and the tested zero-dispersion wavelength and the numerical value are 0.973 μm and 1.018 μm respectively, which well verify the validities of the numerical method and the measurming system.
