Abstract :
Leaky ray attenuation in elliptical graded-index fibres it related to the changes in the ray parameter ¿ that are induced by fibre ellipticity. Parabolic index fibres are described in detail. Results are given for the correction factors which must be applied to the measured near-field intensity in order to obtain the refractive-index profile.
