Birefringence and polarisation mode-dispersion in spun single-mode fibres
Barlow, A.J., Ramskov Hansen, J.J. and Payne, D.N. (1981) Birefringence and polarisation mode-dispersion in spun single-mode fibres. Applied Optics, 20, (17), 2962-2968. (doi:10.1364/AO.20.002962).
A theoretical and experimental analysis of the polarization properties of twisted single-mode fibers is presented. It is shown that whereas a conventionally twisted fiber possesses considerable optical rotation, a fiber which has a permanent twist imparted by spinning the preform during fiber drawing exhibits almost no polarization anisotropy. It is thus possible to virtually eliminate the commonly observed fiber linear birefringence. As a consequence, fibers made in this way are ideally suited for use in the Faraday-effect current transducer. It is further shown that a permanent twist of a few turns/meter effectively eliminates polarization mode-dispersion. The technique therefore appears attractive for enhancing the bandwidth of very long unrepeatered telecommunication links.
