Abstract:
An optical switch comprising:a) an input fiber collimator for receiving a light beam; b) a first mirror optically connected to the input collimator, for receiving the light beam from the input collimator; c) a first galvanometer coupled to the first mirror, for rotating the first mirror around a first axis so as to position the first mirror alternatively to any one of a plurality of first mirror positions; d) a second mirror optically connected to the first mirror, for receiving the light beam from the first mirror; e) a second galvanometer coupled to the second mirror, for rotating the second mirror about a second axis perpendicular to the first axis, so as to position the second mirror alternatively to any one of a plurality of second mirror positions; and f) a two-dimensional array of output fiber collimators each optically coupled to the second mirror, each of the output collimators being aligned with a ray corresponding to one of the first mirror positions and one of the second mirror positions, whereby the light beam is directed to any one of the output collimators by rotating the first mirror and the second mirror.
