Abstract:
1. An optical switching device, comprising: an input light deflection section comprising multiple movable deflection members, each respective deflection member being capable of deflecting a respective input light beam of a plurality of input light beams at one of a plurality of different deflection angles being selected in a same plane, and outputting said deflected input light beam; a collimated light output section capable of reflecting the deflected input light beams deflected by each deflection member and outputting said deflected and reflected light beams as collimated light beams, where each collimated light beam has one of a plurality of optical axes being in a relationship of parallel translation to each other, said one of the plurality of optical axes being defined in accordance with the respective selected deflection angle; and an output direction-path guide section for guiding the collimated light beams from said collimated light output section to respective output direction-paths in accordance with the respective optical axes, wherein said collimated light output section is constituted of a member having a paraboloid-type reflection surface and the deflection members of said input light deflection section are provided at positions of substantially focal points of said paraboloid.
