Abstract
An optical fiber switch (16) for alternatively redirecting an input beam (14) comprises a redirector (18) and a redirector mover (20). The redirector (18) is positioned in the path of the input beam (14) along a directed axis (344A). The redirector (18) redirects the input beam (14) so that a redirected beam (46) alternatively launches from the redirector (18) (i) along a first redirected axis (354) that is spaced apart from the directed axis (344A) when the redirector (18) is positioned at a first position (348), and (ii) along a second redirected axis (356) that is spaced apart from the directed axis (344A) when the redirector (18) is positioned at a second position (350) that is different from the first position (348). The redirector mover (20) moves the redirector (18) about a movement axis (366) between the first position (348) and the second position (350). The redirector mover (20) includes a stator component (320A) and a rotor component (320B) that moves relative to the stator component (320A). The input beam (14) is directed along the directed axis (344A) substantially between the stator component (32A) and the redirector (18) prior to the input beam (14) being redirected …
