Abstract: A one-by-N fiber optical switch is provided wherein an optical signal is transmitted between a common optical fiber and one of a plurality of optical fibers. The one-by-N fiber optical switch includes reflector assemblies that are respectively movable between a first position and a second position to route the optical signal between the common optical fiber and the selected optical fiber. The one-by-N optical switch further includes magnetic reflector assembly movers that create electrically induced magnetic forces to respectively move the reflector assemblies between their first positions and second positions. An N-by-N optical switch can be created by cross-connecting a number of input common optical one-by-N switches with an equal number of output common optical one-by-N switches.

Abstract: An optical switch wherein mirrors move between two positions in order to transmit optical signals between input fibers and output fibers. In a first position, the optical signal is transmitted by input fibers through a one-quarter pitch of Grade Index Refractive (GRIN) lens. The light signal is then reflected by a first mirror and second mirror such that its path carries it to a focusing one-quarter GRIN lens, and to output fibers. With the mirrors in its second position, the optical signal is transmitted directly from input fibers, through one-quarter pitch of Grade Index Refractive (GRIN) lens, to a focusing one-quarter GRIN lens, and to output fibers, thereby resulting in an unreflected light signal path.

Abstract: An optical coupling device for coupling light into a selected output fiber. The input fiber is optically aligned with one of a plurality of output fibers via a reflector. By rotating a reflector about an axis, the input light beam can be reflected to a selected output fiber. The input fiber and all the output fibers are in fixed position relative to each other.
