CA 2228465
A passive optical switching device is disclosed, comprising a guide (2) to which at least two optical fibres (4,6) can be coupled and at least one (and more typically several) optical switching elements (8,10,52) which are each received by the guide (2) and located thereby such as to be moveable between an active position, in which the switching element optically couples a pair of fibres, and an inactive position. This movement is controllable by an electromagnetic actuator (18,20,108). Several such switching elements may be disposed in a matrix defined by the guide. The functional components may be formed by the LIGA technique.
Dispositif de commutation optique passif, comprenant un guide (2) auquel au moins deux fibres optiques (4, 6) peuvent être couplées et au moins un (le plus souvent, plusieurs) élément de commutation optique (8, 10, 52) que reçoit le guide (2) et qui y sont situés de façon à pouvoir aller et venir entre une position active, dans laquelle l'élément de commutation couple optiquement une paire de fibres, et une position inactive. Ce déplacement peut être commandé par un dispositif de commande électromagnétique (18, 20, 108). Plusieurs de ces éléments de commutation peuvent être disposés dans une matrice définie par le guide. Les composantes fonctionnelles peuvent être formées selon la technique LIGA.
