Many optical fibre sensors such as interferometers and gyros require the transmission of stable colinear polarised light. External perturbations such as bends and twists, however, lead to variations in the output polarisation state of light guided by ordinary single-mode optical fibres (Payne et al (1)). Highly birefringent fibres attempt to overcome this difficulty by deliberately introducing levels of intrinsic birefringence Delta beta in excess of that produced by external factors, thereby rendering the polarisation state immune to all but the most major perturbations. Such fibres are characterised by their modal birefringence B, defined as n =lambda /B at a given wavelength
