Popis:	Based on a simple series expansion method involving Chebyshev technique, we predict the cladding decay parameter (W) and the fundamental modal field inside the core as well as cladding in case of single-mode graded index fiber in the low normalised frequency (V) region. The method involves formulation of linear relationship of K 1 (W)/K 0 (W) with 1/W for a few intervals of W, where W < 0.6. With examples of step and parabolic index fibers we show that said predictions by our simple formalism agree excellently with the available exact results. Thus the accuracy of our formalism is established.
