CA 2464139

Methods of calibrating and operating optical switches as well as optical switches in which the orientations of mirrors are measured and controlled using control light beams and position sensing detectors are described. The present invention may provide high resolution control of a plurality of mirrors in an optical switch and thus allow the optical switch to cross- connect a large number of input and output ports with a low insertion loss.

La présente invention concerne des procédés d'étalonnage et de fonctionnement de commutateurs optiques ainsi que des commutateurs optiques dans lesquels les orientations des miroirs sont mesurées et contrôlées au moyen de faisceaux lumineux de contrôle et de détecteurs capteurs de position. La présente invention peut fournir un contrôle haute résolution d'une pluralité de miroirs dans un commutateur optique, permettant ainsi au commutateur optique d'établir le raccordement croisé d'un grand nombre de ports d'entrée et de sortie sans faible perte d'insertion.
