Abstract :
Taking account of the reinjection at the clad/coating interface, we are able to substantially improve the performance of polarizers made by coils of hi-bi fiber. We obtain reproducibly 45 dB of extinction with a 4-turn coil of selected radii, with no kinks in attenuation and a limited insertion loss.<>
