To steer a beam in an optical switch, a collimator joined to an optical fibre along a Z-axis is mounted in a gimbal for rocking movement about X and Y axes. A piezoelectric actuator extends alongthe Z-axis and is symmetric about the fibre. An angular position sensor on the collimator provides feedback for use in steering the beam.

L'invention concerne l'orientation d'un faisceau dans un commutateur optique, qui repose sur l'utilisation d'un collimateur couplé à une fibre optique le long d'un axe Z. Ce collimateur est installé dans un cardan qui donne un mouvement d'oscillation autour d'axes X et Y. Un actionneur piézo-électrique s'étend le long de l'axe Z, en position symétrique autour de la fibre. Un capteur de position angulaire placé sur le collimateur fournit une information en retour pour l'orientation du faisceau.
