Abstract
[Problems to be solved] To provide an optical switching device which can switch between input/output optical paths of input/output ports while suppressing the influence on optical signals passing through other input/output ports. [Means to solve problems] An optical switching device comprises an optical switch arrayfor switching between input/output paths of a plurality of input/output optical fibers. The optical switch arraycomprises a substrate, on which a cantileveris supported. A part of the cantileveron the leading end side is provided with an annular support, which supports a movable mirrorinclinably. The movable mirrorreflects an optical signal from any of the input/output optical fibers toward another input/output optical fiber. The leading end of the cantileveris provided with a comb part. Arranged on the upper face of the substrateare electrodefor tilting the movable mirrorwith respect to the annular supportand an electrodefor moving the movable mirrorin the direction different from the tilting direction of the movable mirror
