  In this paper, we present a solid-core Silica-based photonic crystal fiber
(PCF) composed of hexagonal lattice of air-holes and calculate the effective
index and chromatic dispersion of PCF for different physical parameters using
the empirical relations method (ERM). These results are compared with the data
obtained from the conventional multipole method (MPM). Our simulation results
reveal that the ERM is an accurate and fast method for dispersion analysis of
PCFs with large pitch sizes. However, for small pitch sizes of PCFs, it is not
as accurate as the MPM method. Therefore, ERM is a fast, simple and accurate
method for modeling and analysis of Silica-based PCFs with large pitch sizes.
