Abstract
In this paper the different loss mechanisms of light in multimode fibres are analysed from the point of view of the extinction of leaky skew rays. First, the intrinsic loss mechanism of leaky rays due to optical tunnel effect is fully investigated by means of a quasi-classical approach and a well approximated form of the relative extinction coefficient is derived. Second, the influence of other loss phenomena, due to imperfections or impurities in the fibre such as core and cladding absorption and scattering, on the relative contribution of leaky rays is analysed. Finally some phenomena of failed excitation of leaky rays are also examined. The phenomena are analysed both qualitatively and quantitatively and a comparative analysis of various effects referring to actual fibres is made.
