A new method for calculating the confinement loss of leaky modes in arbitrary microstructured optical fibers is presented. The full vector algorithm is based on a polar coordinate Fourier decomposition method with adjustable boundary conditions, capable of accurately determining the outward radiating fields of the waveguide. Example waveguides with circular and elliptical hole shapes and their leaky mode solutions are presented and discussed.
