PROBLEM TO BE SOLVED: To suppress the warping of a substrate and to prevent the deterioration of optical coupling efficiency so as to obtain a switch by means of a low cost with small insertion loss by forming an optical waveguide path by means of an organic material. SOLUTION: The switch consists of an SUS 304 substrate 8, a cantilever 9 which is formed in the hollow part of the SUS 304 substrate 8 in a mobile state and where a tip is connected, a mobile side optical waveguide 2 formed on the cantilever 9, driving mechanism consisting of a magnetic film 3 and an electromagnetic actuator 4, a fixed side optical waveguide 6 receiving an optical signal from the mobile side optical waveguide 2, an input fiber 1 making light incident to the mobile side optical waveguide 2 and an output side optical fiber 5 taking-out the optical signal from the fixed side optical waveguide 6. The optical waveguide paths 2 and 6 are formed by the organic material in an optical waveguide type optical switch with this kinds of configuration. In the optical switch, the contact part of a connecting member and the substrate is projected from an organic material layer in the both of the connecting members of the optical waveguides 2 and 6 and also the substrate at a position where the connecting members are brought into contact at the time of changing-over an optical path. |
