Abstract
Employing the simple series expression based on Chebyshev technique, we predict the fundamental modal field inside the core as well as cladding in case of dispersion-shifted trapezoidal and dispersion-flattened graded and step W fibers. This formalism also estimates cladding decay parameters (W) of the said fibers. The analysis involves use of a linear relationship of the ratio of first and zero order modified Bessel functions in the form
with 1/W over a wide and practical range of W values appropriate for guidance of only fundamental mode in such fibers. The present method prescribes analytical expressions for the concerned propagation characteristics and these are executable with little computations. Our results are found to match excellently with the available exact results.
