Abstract

A simple geometric-optical theory predicts impulse broadening in multimode fibers using the far-field power distribution of an incoherently excited waveguide with arbitrary refractive-index profile. The accuracy is comparable with that of scalar optical methods if they do not incorporate mode coupling and a differential mode attenuation model.
