Abstract

The variational principle for nonstandard eigenvalue problems recently introduced and used for step-index optical fiber analysis by the present authors is extended to anisotropic graded-index optical fibers. It is seen through an example of a round parabolic-index fiber that the choice of trial functions is more delicate than for the step-index fiber because of the more complicated field function. Certain two-parameter approximants, however, appear accurate enough and can be optimized with a simple calculator or desk computer analysis
