ABSTRACT:
A connecting device is disclosed wherein an end of a fiber is joined to a connecting block which has one side polished and is bonded to a side, also polished, of an integrated optic circuit. The connecting block further has another side, inclined with respect to the its first side, making it possible to illuminate the side of the connecting block and to observe the image of the interference fringes sent back by the interface between the connecting block and the integrated optic circuit. According to the method of the invention, the connecting block is positioned by observing the previous image, and the bonding is then made.
