A photonic crystal fiber (PCF) with a hollow core filled with chloroform (CHCl3) is studied about the dispersion properties. PCF consists eight rings of air-holes with hexagonal shape and CHCl3-core. The dispersion characteristics of the fundamental mode are studied numerically for diffirent geometrical parameters. The numerical simulations were set up with the lattice parameters from 1.0 µm to 2.5 µm, and the linear filling factors from 0.45 to 0.80. The results showed that the dispersion characteristic strongly depend on the geometrical parameters. Furthermore, the zero-dispersion wavelength (ZDWs) can be turned by changing the lattice parameters and the linear filling factors.
