Abstract: An integrated optical component comprising at least one waveguide integrated into a substrate (1) and connected to the end of an optical fiber (2) which is attached to the substrate at said fiber end and in an region separated from said fiber end by a first drop (7) of adhesive and a second drop (8) of adhesive, respectively. The adhesive product which constitutes the first drop has a glass transition temperature located in a predetermined operating temperature range of the component, while the adhesive product which constitutes the second drop has a glass transition temperature located generally above this operating temperature range, thereby assuring the absorption of differential expansions in such a way as to maintain the optical continuity of the fiber/waveguide attachment and the mechanical strength of the fiber/substrate attachment.

Abstract: The component comprises at least one waveguide (5) integrated into a glass substrate (1) and connected to the end of an optical fibre (2) fixed to the substrate at this end and, at a region far from the latter, by, respectively, first (7) and second (8) spots of an adhesive substance. The adhesive substance forming the spot (7) has a glass transition temperature located in a predetermined temperature range for use of the component, whereas the adhesive substance forming the spot (8) has a glass transition temperature located above this temperature range. In this way, differential expansions are absorbed so as to maintain the optical continuity of the fibre/waveguide assembly and the mechanical cohesion of the fibre/substrate connection.
