Abstract
This paper reports on the design and performance of all-fibre polarizers and polarization beamsplitters utilizing both standard and high birefringence optical fibres. These devices exploit the polarization selective coupling of an optical field to a surface plasmon polariton in a thin metal film. In the case of the polarizer the power coupled into the plasmon is dissipated whereas in the polarization beamsplitter it is further coupled into a second optical fibre. High quality devices have been manufactured and extinct-ion ratios in excess of 50dB and 40dB have been achieved for polarizers and polarizing beamsplitters respectively.
