Abstract

Ce dispositif est utilisé pour accoupler optiquement deux fibres optiques opposées 1 et 2. Un premier élément de cristal biréfringent 4 décompose la lumière en rayons séparés ordinaire et extraordinaire. Ces derniers subissent une rotation de leur polarisation de 90 degrés lorsqu'ils traversent vers l'avant un élément magnéto-optique 6 et une lame de compensation 7. Ils sont recomposés par un deuxième élément de cristal biréfringent 5 et sont appliqués ensuite à la fibre optique 2. Par un choix approprié des épaisseurs des éléments 4 et 5, on empêche les rayons ordinaire et extraordinaire transmis dans le sens inverse de se superposer à l'extrémité d'incidence de la première fibre optique, constituant ainsi un isolateur optique. Applications : notamment à l'utilisation des communications par fibres optiques.
