Abstract:
Device allowing the end (4) of an optical fiber (3) to be positioned and held in place inside a substrate (1), wherein: the substrate (1) has a groove (2) intended to accommodate the end (4) of the optical fiber (3), said groove (2) possessing at least one plane wall (8) perpendicular to the principal plane (9) of the substrate (1); the groove (2) includes a moveable part (5), located on the face opposite the plane wall (8) and capable of moving toward said plane wall (8) between two positions, namely; a retracted position in which the end of the optical fiber (3) can penetrate freely into the groove (2); a locked position in which the moveable part (5) comes into contact with the optical fiber (3) in order to press it against said plane wall (8); it includes means (21, 24) allowing a force to be exerted on the moveable part (5) in order to cause it to move with respect to the plane wall (8)
