Abstract :
It is suggested that the method of analysing inhomogeneous monomode fibres in terms of moments of the refractive-index profile can be generalised to provide a simple characterisation of noncircular fibres with arbitrary cross-sectional shape and refractive-index profile. For example, it is shown that the second mode cutoff in a rectangular fibre can be obtained directly from the corresponding result for a circular fibre.
