Abstract :
A fibre with strong elliptical birefringence can be obtained by spinning a linearly birefringent fibre during the draw. Theoretical and experimental results show that such fibres are particularly useful for magnetic field and electric current sensing, since they are resistant to external mechanical perturbations.
