ABSTRACT: An exact and fast analytic method based on power series
is established to predict the modal field distributions, Petermann-2
spot size, the normalized propagation constant corresponding to fundamental and
first higher order mode in graded index fibers with any arbitrary power law
profile. The variation of normalized cut-off frequencies of some LPlm modes in graded index fibers with different profile exponents are also shown
here and an empirical relation between them is determined.
