PURPOSE:To provide an optical switch to carry out a positioning work efficiently by detecting accurately the fine movement direction or the distance of an optical waveguide to be positioned so as to make optical axes coincide with each other. CONSTITUTION:An optical switch is provided with a master side connector 3 having a master fiber 4 to emit signal light (lambda1) and an optical fiber 9 to project illumination light to a coupling edge surface 1c. Beam splitters 6 and 11 to couple the emitted signal light with the illumination light, a PSD (position detector) 13 and so on are provided in the master side connector 3. Though an image on the coupling edge surface 1c is formed in the PSD 13, since this image becomes a bright and dark image corresponding to a core part 1a and a clad part 1b, the master side connector 3 is set to be positioned relatively to an optical fiber 2 so that an image of the core part 1a can be positioned at a specific position of an image receiving surface 13a. |
