All-fiber controller of radial polarization using a periodic stress

Djamel Kalaidji, Michel Spajer, and Thierry Grosjean

Abstract :

Our aim is to transpose the polarization control by mechanical stress, usually applied to single-mode fibers, to the(TM01,TE01,HEev21,HEod21) annular mode family. Nevertheless, the

quasi-degeneracy of these four modes makes the situation more complex than with the fundamental mode HE11 . We propose a simple device based on periodic perturbation and

mode coupling to produce the radially polarized TM01 mode or at least one of the four modes

at the extremity of an arbitrarily long fiber, the conversion to TM01 mode being achievable by

classical crystalline plates.
