Optical switch using an annular array of optical ports

摘要

An optical switch and method of switching provide 1xN optical switching. The optical switch comprises a plurality of optical ports arranged in an annular pattern visible to and aligned with a movable mirror. The mirror is equidistant from each port of the plurality. The optical switch having a 1-dimensional (1D) annular array of ports comprises the mirror located at a center of a circle and the 1D array disposed on a portion of a circumference of the circle. The optical switch having a 2-dimensional (2D) annular array of ports comprises the mirror located at a center of a sphere and the 2D array disposed on a portion of a surface of the sphere. The mirror is movable about one or more axes to direct an optical signal from any port to any other port of the plurality.
