Light deflector and the optical deflecting device

Light deflecting element comprises a substrate made of electro-optical material, an optical waveguide film of the optical waveguide formed on the substrate, it is arranged on the incident side of the optical waveguide layer so as to face the thickness direction of the Hikarishirubehamaku , a light beam propagating through Hikarishirubehamaku, a first pair of electrodes for deflecting the in-plane direction of the optical waveguide film according to the first applied voltage, light opposite to the thickness direction of the Hikarishirubehamaku Shirubehamaku disposed on the output side, the light beam deflected in the plane direction of the optical waveguide layer by the first electrode pair, a second electrode for deflecting the film thickness direction of the optical waveguide film according to the second applied voltage and a pair second electrode pair includes a first electrode, a second electrode, the first electrode and the second electrode, different in the traveling direction of the light beam propagating the Hikarishirubehamaku It is formed in length.
