Abstract
Abstract Deformation effects in the fibres are overcome by inducing a longitudinal axis torsional distortion such that the polarisation sense is altered with respect to the axis of the fibre cross-section elipse. Polarisation alteration is continuous and uniform over the whole fibre length. The difference in transit time for the light waves in the two optical axes senses remains small due to continuous phase changes, the sign of the difference between the two partial waves varying over the fibre length. Torsional distortion is induced into the fibre initially prior to being wound into a helical coil which can then be bent into a toroid.
