The present invention includes a tool ( ) for positioning optical waveguide fibers ( ) on an adhesive coated substrate ( ) including a holder ( ) and a pressure source. The holder ( ) includes a chamber ( ) coupled to the pressure source and multiple recesses ( ) configured to position the optical waveguide fibers ( ). Each recess ( ) includes a reference surface ( ) and is connected to the chamber ( ) by a passageway ( ). The pressure source is configured to selectively increase and decrease the pressure in the chamber ( ). The invention also includes a method of making optical waveguide fiber array blocks using the tool ( ).

Method for positioning optical fibers

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.
