  • Abstract
    Cutoff frequencies of the guided modes in a graded-index fibre with a finitely thick cladding are calculated by a refined WKB method. The results are in good agreement with the exact ones for the parabolic core fibre. The effect of the fourth order correction to the parabolic core fibre on the cutoff frequency is evaluated.
