Patent ID: 7725001

Claim:
A device for coupling an optical fiber, comprising: a first surface and a second surface, the first and second surfaces comprising respective active surface portions; a ridge having a groove longitudinally extending along the top of the ridge, wherein said second surface lies on the groove; and at least one optical fiber positioning element adapted to position at least one point of an optical fiber on a longitudinally median plane of said second surface, wherein the first and second surfaces are movable relative to each other between a first and a second relative position, the first and second surfaces, when in the second relative position, cooperating to accommodate a section of the optical fiber therebetween, so that the first and second active surface portions cooperate to keep the optical fiber in a predetermined bent condition; and wherein, 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 said median plane.
