Modelling microstructured optical fibres

In this paper we present an analysis and design of the microstructured optical fibres using the effective index and the Galerkin models. Some performance of air guiding microstructured fibers is discussed. We establish the effective indexes, field distributions and chromatic dispersion of the guided modes. We demonstrate that the full-vectorial Galerkin method can be efficiently used to obtain the propagation characteristics of microstructured optical fibres. Comparison with previous models and numerical methods is made and excellent agreement is achieved.
