An optical routing device is described that comprises a semiconductor substrate (52) having at least one optical input (4), a plurality of optical outputs (6,8) and an array of MEMS moveable reflective elements (58;102). The array of moveable reflective elements (58; 102) are configurable such that light can be selectively routed from any one optical input (4) to any one of two or more of said plurality of optical outputs (6,8). Light selectively routed from any one optical input to any one of two or more of said plurality of optical outputs (6,8) is guided within a hollow core waveguide (54). In one embodiment, a cross-connect optical matrix switch is described.

L'invention concerne un dispositif de routage optique comprenant un substrat semi-conducteur (52) possédant au moins une entrée optique (4), plusieurs sorties optiques (6, 8) et un réseau d'éléments réfléchissants mobiles MEMS (58; 102). Ce réseau d'éléments réfléchissants mobiles (58; 102) peut être configuré de manière que la lumière puisse être acheminée de façon sélective de n'importe quelle entrée optique (4) vers n'importe laquelle des sorties optiques (6, 8). La lumière acheminée de façon sélective de n'importe quelle entrée optique vers n'importe laquelle des sorties optiques (6, 8) est guidée dans un guide d'ondes central creux (54). Un mode de réalisation de cette invention concerne un commutateur matriciel optique de répartition.
