CA 2366200

An optical network assembly includes a planar lightguide circuit (PLC) (210) and a filtering device (220). A PLC can have at least two optical paths (230, 240) for propagating optical energy. The PLC can be designed to channel optical energy with its optical paths towards the filtering device (220) in order to separate the optical energy into at least two beams, where a first beam can contain a first information channel and a second beam can contain a second information channel. The filtering device can be attached directly to the PLC or it can be attached directly to an optical waveguide that is also connected to the PLC. The optical waveguide can either feed optical energy to or propagate optical energy away from the PLC. Multiple optical waveguides can be attached to a PLC to feed optical energy into and away from the PLC. The PLC, filtering device, and optical waveguide can form the building blocks to more complex optical network architectures.

L'invention concerne un ensemble pour réseau optique comprenant un circuit plan guidant les ondes optiques (PLC) (210) et un dispositif de filtrage (220). Un PLC comporte au moins deux chemins optiques (230, 240) permettant la propagation de l'énergie optique. Le PLC peut être conçu pour orienter l'énergie optique à l'aide de ses chemins optiques vers le dispositif de filtrage (220) afin de séparer l'énergie optique en deux faisceaux au moins, le premier faisceau pouvant contenir un premier canal d'information et le deuxième, un deuxième canal d'information. Le dispositif de filtrage peut être directement relié au PLC ou à un guide d'ondes optiques lui-même connecté au PLC. Le guide d'ondes optiques peut soit diriger l'énergie optique vers le PLC, soit l'en éloigner. De multiples guides d'ondes optiques servant à introduire de l'énergie optique dans le PLC ou à l'en éloigner peuvent être reliés au PLC. Le PLC, le dispositif de filtrage et le guide d'ondes optiques peuvent constituer les composants de base de réseaux optiques ayant une architecture plus complexe.
