Abstract
The present invention relates to an optical switching device capable of reducing the number of members such as a movable mirror for reflecting light beams to a relatively small number and suppressing the deterioration of the yield. The optical switching device is configured so as to include an input light deflection section capable of outputting a light beam as a deflected light beam at a plurality of different angles on the same plane, a collimated light output section capable of outputting the deflected light beam from the input light deflection section as a collimated light beam having passed any one of optical axes in a relationship of parallel translation to each another in accordance with the angle, and an output direction-path guide section for guiding the collimated light beam from the collimated light output section to the output direction-path in accordance with the optical axis.
