Abstract

When a highly-birefringent fibre is bent and/or tapered, a large differential loss occurs between the two linearly polarised modes, and this effect. can be used to construct high performance polarisers. The present work compares the perfor-mance and limitations of polarisers made from coils and tapers. Taper polarisers with 35dB extinction have been made, whereas coil polarisers have yielded up to 62dB.
