Low-loss and highly birefringent single polarisation fibres have been fabricated. The minimum transmission loss and the modal birefringence of the fibre with refractive-index difference Δ=0.61% was 0.62 dB/km at λ=1.52 μm and 8.5×10−5 at λ=1.15 μm, respectively. The state of linear polarisation was stable against the handling conditions such as bending, twists, concentrated force, and temperature variations.
