An optical component may comprise a horizontal member (101) with two side walls (108) and a substantially transparent end wall (100) protruding from the horizontal member. The end wall, side walls and horizontal member may partially enclose an interior volume (106), and optical functionality is imparted in any suitable manner on at least a portion of the end wall. An optical assembly may comprise such an optical component mounted on a waveguide substrate (200) along with a planar waveguide (250) and a second waveguide (210, 230), which are end-coupled by either reflection from the optical component end wall or transmission through the optical component end wall. An end portion of a planar waveguide may be received within the interior volume of the mounted component. Proper positioning of the optical component relative to the waveguides may be facilitated by alignment surfaces and/or alignment marks (124, 224) on the component and/or waveguide substrate.

L'invention concerne un composant optique pouvant comprendre un élément horizontal à deux parois latérales et à paroi terminale sensiblement transparente, protubérante depuis l'élément horizontal, enserrant partiellement un volume intérieur. Une fonctionnalité optique est conférée de manière appropriée quelconque au moins à une partie de la paroi terminale. Un ensemble optique peut comprendre ce composant monté sur un substrat de guide d'ondes, avec un guide d'ondes plat et un second guide d'ondes, lesquels sont couplés en extrémité par réflexion depuis la paroi terminale du composant optique ou transmission à travers cette paroi. Une extrémité du guide d'ondes plat peut être logée dans le volume intérieur du composant monté. On peut faciliter le bon positionnement du composant optique par rapport aux guides d'ondes au moyen de surfaces d'alignement et/ou de marques d'alignement sur le composant et/ou le substrat du guide d'ondes.
