  • Abstract
    An appropriate elliptic-core fibre theory is applied to model the differential phase shift between the first- and second-order modes observed in recent experiments on two-mode elliptic-core fibres subjected to longitudinal strains. The theory provides an explanation of the polarisation dependence of the stretching delta l2 pi required to produce a 2 pi differential phase shift between the two modes as a function of wavelength for both polarisations.
