Abstract

Single-mode fibers which are able to transmit a stable, linear polarisation state are of interest for use in coherent detection systems and in fiber interferometers. Fibers in which very high birefringence has been induced, usually by introducing a large asymmetric stress distribution, are relatively immune to external factors which disturb the polarisation state in conventional fibers. They are therefore able to sustain a single linearly polarised mode over long lengths.
