Abstract
Experimental results are presented which show that the fundamental mode in highly birefringent fibres is not plane-polarised, as is normally assumed, but has significant orthogonal field components. These components limit the maximum measurable polarisation intensity extinction ratio to ∼40 dB. Implications for polarisation measurements and fibre gyros are outlined.Keywords
