An optical device (20), and a method of producing the device (20), are disclosed. The device (20) comprises a substrate (22) and an optical waveguide (24) component affixed to the substrate with a glass frit fusion seal (34) formed and locked within a recessed void in the substrate, the glass frit fusion seal being the fused product of a low melting glass frit. The recessed void in the substrate includes a region for receiving the optical waveguide component (24) and an intersecting region that secures the placement of the glass frit fusion seal (34). The optical waveguide component (24) is affixed to the substrate in order to control temperature varying optical properties of the component.
L'invention concerne un dispositif optique (20) et un procédé de fabrication correspondant. Le dispositif (20) comprend un substrat (22) et un guide d'onde optique (24) fixé au substrat, avec un joint par fusion de fritte de verre (34) formé et encastré dans une cavité libre du substrat. Ce joint est obtenu par la fusion de fritte de verre à faible point de fusion. La cavité susmentionnée comporte un logement pour le guide d'onde optique (24) et une région d'intersection permettant d'assurer la mise en place du joint (34) considéré. On fixe le guide d'onde optique (24) au substrat de manière à pouvoir contrôler les propriétés optiques de ce guide d'onde qui varient en fonction de la température.
