Comparative study of numerical methods used in modeling of photonic crystal fibers

In this article, we present a performance comparison, in terms of accuracy and computational cost, of the numerical techniques used in the resolution of the models of photonic crystal fibers.These models allow to obtain the electromagnetic field distributions and, once known this one, the dispersion parameter and the nonlinear coefficient. In this study, we conclude that the central finite difference scheme of fourth order would be the most advantageous. © 2013 Wiley Periodicals, Inc.
