title: Dispersion properties of liquid-core photonic crystal fibers.
abstract: Dispersion properties of liquid-core photonic crystal fibers (PCFs) with large air fraction in clads between 300 to 2000 nm have been calculated by a multipole method for various liquids including CS(2), toluene, chloroform, and water for different core diameters. In calculations, air holes are assumed to be arranged in a regular hexagonal array in fused silica, and a central hole is filled with liquid to create a core. The results are compared with those obtained by a fully vectorial effective index method, and fitting parameters for core sizes are found for each liquid except for water, where the latter method does not give correct dispersions at short wavelengths. Also, the power ratios inside liquid cores and effective core areas were calculated at different wavelengths.
