Abstract

Approximated analytic solutions for wave propagation in graded-index optical fiber have been found in the case of a parabolic profile. Approximants with high accuracy are presented that are much better than those found by other authors. A two-point quasi-rational method and two-point Padé approximants are used in this work. The approximants are explicitly determined for the azimuthal eigenvalues $ l = 0, 1, 2$ and the mth mode numbers $ m = 0, 1, 2, 3$.
