Patent

CA 2286648

A planar optical waveguide with a liquid filled wave guiding region (2), which may be straight, coiled or otherwise folded, with filling channels (3) provided transversely along its length. The wave guiding region may be fabricated in a substrate (1) with a reservoir (22) on the substrate to facilitate filling through the filling channels. A Mach-Zhender configuration optical switch using a liquid filled waveguide is also described.

L'invention porte sur un guide optique plan comportant une région (2) de guide d'onde remplie de liquide, ce guide d'onde pouvant être droit, sous forme d'enroulement ou plié, et des canaux de remplissage étant formés transversalement sur sa longueur. La région de guide d'onde peut être formée dans un substrat (1) pourvu d'un réservoir (22) de sorte que le remplissage par les canaux s'effectue facilement. L'invention porte également sur un commutateur optique à configuration Mach-Zhender utilisant un guide d'onde rempli de liquide.
