A continuous model for mode mixing in graded-index multimode fibres with random imperfections

Perrey-Debain, Emmanuel; Abrahams, I. David; Love, John


This article investigates the evolution of the distribution of propagating modes in a graded-index multimode fibre with random imperfections. These perturbations may be microscopic random bends and ellipticity, or an index of refraction fluctuations, introduced during manufacture. For large-diameter fibres (with respect to a typical electromagnetic wavelength), the number of guided modes becomes large, and so we can regard the discrete set as a continuum in which the mode number is treated as a...[Show more]
