Abstract
(EN)
Disclosed is an optical interconnection device that includes an alignment ferrule assembly formed from an alignment substrate and optical fibers. The optical interconnection device also has an alignment assembly formed by a planar support member with guide features. A receiving region resides between the guide features in which the alignment substrate is secured. An evanescent optical coupler can be formed using the optical interconnection device as a first device and another optical interconnection device as a second device. The second device is constituted by a planar lightwave circuit that operably supports waveguides and an adapter. The adapter of the second device is configured to engage the alignment assembly of the first device to place the optical fibers and the optical waveguides of the respective devices in evanescent optical communication.

L'invention concerne un dispositif d'interconnexion optique qui comprend un ensemble de viroles d'alignement formé à partir d'un substrat d'alignement et de fibres optiques. Le dispositif d'interconnexion optique comprend également un ensemble d'alignement formé par un élément de support plan avec des éléments de guidage. Une région de réception réside entre les éléments de guidage dans lesquels le substrat d'alignement est fixé. Un coupleur optique évanescent peut être formé en utilisant le dispositif d'interconnexion optique en tant que premier dispositif et un autre dispositif d'interconnexion optique en tant que second dispositif. Le second dispositif est constitué d'un circuit d'onde lumineuse plan qui supporte de manière fonctionnelle des guides d'ondes et un adaptateur. L'adaptateur du second dispositif est configuré pour venir en prise avec l'ensemble d'alignement du premier dispositif pour placer les fibres optiques et les guides d'ondes optiques des dispositifs respectifs dans une communication optique évanescente.
