A Comparative Study of Multipole and Empirical Relations Methods for Effective Index and Dispersion Calculations of SilicaBased Photonic Crystal Fibers

In this paper, we present a solidcore Silicabased photonic crystal fiber (PCF) composed of hexagonal lattice of airholes 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 modelling and analysis of Silicabased PCFs with large pitch sizes.
