Abstract
An integrated optical component comprising at least one waveguide integrated into a substrate and connected to the end of an optical fiber which is attached to the substrate at said fiber end and in a region separated from said fiber end by a first drop of adhesive and a second drop 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.
