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 δl2π required to produce a 2π differential phase shift between the two modes as a function of wavelength for both polarisations |
