Abstract (en)

[origin: WO02056096A2] Devices and methods for switching transmission of light from one optical fiber (450) to another (460). A steerable fiber (430) has an end (432) in a capsule (404, 406), as do one or more cooperating fibers (450, 440). Initially steerable fiber (430) is at a rest position, from where it couples light into one of the cooperating fibers (450). The end (432) of the steerable fiber (430) includes an armature (435) that moves in response to applied magnetic fields. Then a magnetic field is generated selectively, and a pair of pole pieces (420) transfers it to a location (424) inside (408) the capsule, which is close to the armature (435). Thus the end (432) of the steerable fiber (430) is moved to another position, from where it couples light into the other cooperating fiber (440).
