Abstract

The power transmitted within multimode circular optical fibres illuminated at one end by either coherent or incoherent light is determined. In general, a significant portion of this power is due to the radiation field even kilometres from the source. Thus an analysis in terms of bound modes alone is inadequate and so is geometric optics using Fresnel's lawS. Instead, we use a modified form of geometric optics in which the rays are appropriately weighted to account for the leakage (radiation) from the fibre not included by Fresnel's laws. Extensive numerical results are given.
