Abstract :
A simple formula for the attenuation constant of leaky modes in a generalised class of noncircular graded-index fibres is derived both from geometrical optics and a WKB method. The leaky mode attenuation in near-parabolic profile fibres is shown to increase rapidly with increasing eccentricity of the fibre.
