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.
