Abstract

The cutoff frequencies of guided modes in a weakly guiding W-type fibre with parabolic core profile have been obtained. It is found that the cutoff frequency of the TE₀₁-mode in such a fibre is much higher than for a homogeneous-core W-type fibre. This should allow greater ease in splicing.
