Abstract(in Japanese) (See Japanese page)
Abstract(in English) Laser beams injected into a BaTiO_3-crystal cross and make gratings that diffract the beams. The direction of the diffracted laser beams can be controlled by controlling the laser beams' injection conditions realizing optically controlled switching. In order to apply this switching phenomenon to optical rout switching devices, the following experiments have been performed: digital signal transfer, switching speed dependence on crystal temperature and switching dependence on polarization.
