Fabrication of single-mode fibres exhibiting extremely low polarisation birefringence

An investigation of the relative effects of core ellipticity and stress-induced birefringence on fibre polarisation properties is described. It is found that a reduction in core stress levels is necessary to obtain low-birefringence fibres. A fibre having a retardation of only 2.6°/m is reported.
