Abstract

Continuous metal/glass fibre polarisers incorporating Ga or In/Sn alloy have been fabricated. An extinction ratio of greater than 37 dB with an insertion loss of less than 1 dB can be obtained over a 250 nm spectral window around 1300 nm. Extinction ratios as high as 52 dB have been measured at 830 nm.
