Analysis of a beam propagation in optical fiber structures with high step index

Microstructural fibers with high steps of the refractive index require special methods to calculate light propagating. In this paper three numerical methods describing beam propagation are compared. This comparison is shown for a two-core cylindrical waveguide.
