Patent attributes
A device for coupling an optical fiber includes: a first surface and a second surface, including respective active surface portions; at least one optical fiber positioning element adapted to position at least one point of an optical fiber on a longitudinally median plane of the second surface. The first and second surfaces are movable relative to one another between a first and a second relative position, and, when in the second relative position, cooperate to accommodate a section of the optical fiber therebetween. In this position, the first and second active surface portions cooperate to keep the optical fiber in a predetermined bent condition, particularly adapted to extract light from, or inject light into, the optical fiber. In at least a part of the relative movement from the first to the second relative positions, the first surface rotates with respect to the second surface around a rotational axis oriented transversally with respect to the median plane.
