Title (EN) OPTICAL FIBER POLARIZATION CONTROLLER
(FR) DISPOSITIF DE COMMANDE DE POLARISATION A FIBRES OPTIQUES
Abstract:
(EN) An optical fiber polarization controller is disclosed which has compact size by employing wave plates made of short sections (110, 120) of a birefringent optical fiber. The optical fiber polarization controller controls the polarization state of input light by twisting or rotating birefringent slices (110, 120) connected to conventional single-mode fibers (100).
(FR) Dispositif de commande de polarisation à fibres optiques qui est compact du fait qu'il comporte des lames d'onde constituées de courtes parties (110, 120) d'une fibre optique biréfringente. Ledit dispositif commande l'état de polarisation de lumière entrante par torsion ou rotation des tranches (110, 120) biréfringentes connectées à des fibres (100) monomode classiques.
