In this paper, we demonstrate that eigen mode expansion can be used successfully to find the propagation constants and field distributions for the modes in an optical fiber. Instead of using sine-functions, we use Bessel functions as the basis for the expansion of the modes. Comparison between the results of this method and the exact analytical results for a single-mode, step-index optical fiber is shown. Also, theoretical and experimental results for a commercial boron co-doped germano-silicate fiber are compared.
