PROBLEM TO BE SOLVED: To provide an optical cross-connector which solves the problems of the small size, simple constitution, high reliability and cost effectiveness of the device for optically cross-connecting optical waveguide multiple signals. SOLUTION: The address light having the wavelength different from that of input light is addressed by an optical shutter in accordance with the route information of the input light and output light and holograms can be recorded and erased at intersection points. After the recording of the hologram, the input light is reflected by the addressed holograms and is outputted to the prescribed output light waveguides. |
