An analytical approximation for the modal field of a single mode index-guiding microstructured fiber is developed using the variational principle. Unlike the equivalent step-index model, our model has the periodic features that are essential part of the field of such microstructure fibers. Using this model, we deduce other important characteristics of these fibers.
