PURPOSE:To obtain a less-loss optical switch which has improved array precision by providing plastic optical waveguides with curved optical waveguides so that respective light guides cross both surfaces of a base material mutually. CONSTITUTION:Optical fibers 26-29 are connected to the plastic optical waveguides 19 and 20 at a fixed part 24. When a movable part 23 is positioned as shown in a figure, a optical signal from an optical fiber for transmission is supplied to an optical receiver 5 through the optical fiber 26, optical waveguide 19, and optical fiber 27. The optical signal after signal processing is led out from an optical transmitter to the optical fiber for transmission through the optical fiber 28, optical waveguide 20, and optical fiber 29. Then when the movable part 23 moves as shown by an arrow A, the optical signal from the optical fiber 2 for transmission is led out to the optical fiber 2 for transmission again through the optical fiber 26, optical waveguid 21, and optical fiber 29 to obtain a by-pass state. |
