ている。As conventional optical path switching bags W, various types of prisms, reflectors, rod lenses, or combinations thereof have been proposed.
第４図に、ロッドレンズとプリズムとを組合ゎせた光路
切替装置を示す。FIG. 4 shows an optical path switching device that combines a rod lens and a prism.

A prism 8 is attached to the end face of the loft lenses 84 to 86 on the opposite side.
7 is placed. By moving the position of the prism 870, it becomes a one-to-two optical switch that guides the incident light from the central optical fiber 82 to either one of the optical fibers 81 and 83 on both sides.
また、第５図は、光導波路と反射板とを組合わせた光路
切替装置を示す。Moreover, FIG. 5 shows an optical path switching device that combines an optical waveguide and a reflection plate.
複数の光導波路９１と別な光導波路９２を互いに所定の

0, there are multiple intersections between the optical waveguide 91 and the optical waveguide 92. By inserting a reflecting plate 93 at a desired intersection among these plurality of intersections, it becomes a matrix switch with n opposing sides, and optical paths can be switched.
〔発明が解決しようとする問題点〕
