CA 2298778

A compound waveguide device (10) having a channel waveguide (60) in optical proximity to an elongate waveguide (30) propagating an optical signal therein is disclosed. The channel waveguide (60) includes a coupling surface through which optical energy is evanescently coupled to or from the optical signal propagating in the elongate waveguide (30). The channel waveguide (60) is shaped to confine distribution of the optical energy therein along axes transverse to the axis of propagation of the optical energy. Transverse diffraction of the optical energy within the channel waveguide (60) is thereby limited. In one embodiment, the elongate waveguide (30) is a side-polished fiber optic waveguide. Electro-optic control of the compound waveguide is disclosed, as are bandstop, bandpass and detection configurations thereof.

L'invention concerne un dispositif (10) de guide d'ondes composé comportant un guide d'ondes à canal (60) à proximité optique d'un guide d'ondes allongé (30) y propageant un signal optique. Le guide d'ondes à canal (60) comprend une surface de couplage par laquelle une énergie optique se couple de manière évanescente en amont ou en aval du signal optique en propagation dans le guide d'ondes allongé (30). Le guide d'ondes à canal (60) est conçu de manière à limiter la répartition de l'énergie optique à l'intérieur, le long d'axes transversaux à l'axe de propagation de l'énergie optique. Ainsi, la diffraction transversale de l'énergie optique à l'intérieur du guide d'ondes à canal (60) reste limitée. Dans un mode de réalisation, le guide d'ondes allongé (30) est une fibre optique polie latéralement. L'invention concerne également une commande électro-optique du guide d'ondes composé, ainsi que des configurations coupe-bande, passe-bande et de détection du guide d'ondes.
