A fiber polarizer has been made using an etched D-shaped fiber coated with indium. For a 39-dB extinction ratio, 0.2-dB loss has been obtained. An analysis shows that the effect of coupling between the polarized modes within the polarizer is to produce a saturation in the observed extinction ratio beyond a critical length.
