Propagation in curved multimode cladded fibres
Propagation in curved multimode cladded fibres
An analysis is given of coupling between modes in a curved, cylindrical, multi-mode optical fibre and very simple form for the coupling coefficients are obtained. In general HE modes and coupling to higher modes can, to first order, be neglected. The degree of mode conversion is largely restricted to a periodic exchange of energy, between these few modes, along the length of the fibre with a periodicity which can be less than 1mm. Excellent agreement is obtained between theory and experiment. This form of quasi-single-mode operation is reflected in very low values of pulse dispersion but is very sensitive to stress in the fibre. The significance of these results in terms of mode conversion is discussed.

Abstract
An analysis is given of coupling between modes in a curved, cylindrical, multi-mode optical fibre and very simple form for the coupling coefficients are obtained. In general HE modes and coupling to higher modes can, to first order, be neglected. The degree of mode conversion is largely restricted to a periodic exchange of energy, between these few modes, along the length of the fibre with a periodicity which can be less than 1mm. Excellent agreement is obtained between theory and experiment. This form of quasi-single-mode operation is reflected in very low values of pulse dispersion but is very sensitive to stress in the fibre. The significance of these results in terms of mode conversion is discussed.
