The dispersion property of a novel photonic crystal fiber with square array air holes was simulated with the vectorial beam propagation method. The impacts of the pitch and hole diameter on the effective area of fundamental mode and the dispersion parameter were evaluated. The results indicate that the effective refractive index decreases and the dispersion parameter increases with air hole diameter increasing and the pitch decreasing, the structure parameters of inner three rings air hole influences the dispersion characteristics greatly. Thus the dispersion property of the photonic crystal fiber can be tailed by the structural parameters.

This study proposes a photonic crystal fiber made of fused silica glass, with the core infiltrated with chloroform as a new source of supercontinuum (SC) spectrum. We numerically study the guiding properties of the fiber structure in terms of characteristic dispersion and mode area of the fundamental mode. Based on the results, we optimized the structural geometries of the CHCl3-core photonic crystal fiber to support the broadband SC generations. The fiber structure with a lattice constant of 1 μm, a filling factor of 0.8, and the diameter of the first-ring air holes equaling 0.5 μm operates in all-normal dispersion. The SC with a broadened spectral bandwidth of 0.64 to 1.80 μm is formed by using a pump pulse with a wavelength of 850 nm, 120 fs duration, and power of 0.833 kW. That fiber would be a good candidate for all-fiber SC sources as cost-effective alternative to glass core fibers.
