    摘要： [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 array 6 for switching between input/output paths of a plurality of input/output optical fibers. The optical switch array 6 comprises a substrate 8, on which a cantilever 11 is supported. A part of the cantilever 11 on the leading end side is provided with an annular support 12, which supports a movable mirror 7 inclinably. The movable mirror 7 reflects an optical signal from any of the input/output optical fibers toward another input/output optical fiber. The leading end of the cantilever 11 is provided with a comb part 14. Arranged on the upper face of the substrate 8 are electrode 15a, 15b for tilting the movable mirror 7 with respect to the annular support 12 and an electrode 16 for moving the movable mirror 7 in the direction different from the tilting direction of the movable mirror 7.

    摘要： The optical multiplexer/demultiplexer 100 includes a member 110 on which optical waveguides 111 to 114 and a groove 115 are formed and an optical filter 120 inserted in the groove 115. The member 110 is a planar optical waveguide where the optical waveguides 111 to 114 are formed on one surface thereof, and the groove 115 is formed thereon. Before the groove 115 is formed, the optical wave guide 111 and the optical waveguide 114 are a continuous optical waveguide; and the optical waveguide 112 and the optical waveguide 113 are a continuous optical waveguide. A straight groove 115 is formed so as to go through an intersecting point of the two continuous optical waveguides. The optical waveguides 111 and 114 are formed straightly on the member 110.
