Highly-elliptically birefringent fibres have been obtained by spinning a linearly-birefringent fibre during the draw. These fibres are particularly interesting for use in Faraday-effect fibre current monitors, since, in contrast with conventional fibres, they can be wound in small multi-turn coils and retain their sensitivity. We show that here the fibre output state of polarisation can be controlled to compensate for environmental perturbations using only one remote active element. Using a compact 80-turn fibre coil, currents up to 370 A rms have been measured, with a maximum sensitivity of 100pA rms Hz-.
