Abstract
The optical switch includes input optical fibers, output optical fibers, a lens, a movable mirror, and an actuator operative to move the mirror. Depending on a voltage applied to the actuator, the actuator selectively set the mirror to a first position corresponding to a first combination of optical paths, through which the light beam travels from the first set of the input optical fibers to the second set of the output optical fibers; and to a second position corresponding to a second combination of optical paths, through which the light beam travels from the first set to the second set. The first combination is different from the second combination, and a number of optical fibers of the first set and the second set is more than two.
