Abstract :
At z = 0 a power distribution may be excited by a Gaussian TEM00 beam in a parabolic-index fibre in which each group of modes with a given propagation constant carries the same power as prescribed by Olshansky´s steady-state distribution. This power distribution, however, still depends on both mode numbers ¿, ¿. Such an excitation may be advantageous for measuring losses in fibres and coupling elements.
