Abstract

Abstract Translated from French Dispositif de connectique dans lequel une extrémité d'une fibre (1) est rendue solidaire d'un bloc de connexion 2 dont une face (20) est polie et est collée contre une face (30), également polie, d'un circuit optique intégré. Le bloc de connexion possède en outre une face 21, inclinée par rapport à la face (20) du bloc de connexion, permettant d'éclairer la face (20) du bloc de connexion et d'observer l'image des franges d'interférences renvoyée par l'interface situé entre le bloc de connexion et le circuit optique intégré. Selon le procédé de l'invention, le bloc de connexion est mis en position par observation de l'image précédente et l'on effectue ensuite le collage. Connection device in which one end of a fiber (1) is made integral with a connection block 2, one face (20) of which is polished and is glued against a face (30), also polished, of an integrated optical circuit. The connection block also has a face 21, inclined relative to the face (20) of the connection block, making it possible to illuminate the face (20) of the connection block and to observe the image of the interference fringes returned by the interface located between the connection block and the integrated optical circuit. According to the method of the invention, the connection block is placed in position by observation of the previous image and then bonding is carried out.
