Abstract :
An all-fibre polariser is demonstrated utilising the birefringent properties of a nematic liquid crystal having refractive indices compatible to that of fused silica. The polariser exhibits an extinction ratio in excess of -45 dB and a loss of 0.2 dB over a temperature range between 10 and 50°C. Design considerations to achieve a desired extinction ratio are also discussed
