Abstract:
1. An optical switching device comprising: a plurality of ports comprising: a stationary reflector for receiving the first optical signal from a first port of the first group of ports and the second optical signal from a first port of the second group of ports, and for substantially reflecting the first and second optical signals towards the plurality of ports; a lens disposed between the plurality of ports and the stationary reflector for substantially collimating the first and second optical signals at the stationary reflector, and for substantially focusing the first optical signal about the first group of ports, and the second optical signal about the second group of ports; and a movable refractor selectably positionable at two positions in and out of optical paths of the first and second optical signals between the plurality of ports and the stationary reflector, wherein the first group of ports is positioned between ports of the second group of ports, and the first group of ports and the second group of ports are mutually optically decoupled, so that to be substantially optically isolated when the movable refractor is in any one of the two positions, thereby providing dual switch functionality.
