Abstract :
Summary form only given. The self-bending effect consists in the propagation of a light beam along a curved path in photorefractive crystals with a large diffusion (gradient-type) nonlinearity. The self-bending effect has been observed in bulk materials such as LiNbO/sub 3/, KNbO/sub 3/ and BaTiO/sub 3/. In all these cases the light is extraordinary polarized and propagates perpendicular to the c/spl I.oarr/ axis. We present experimental results on the double deflection of a gaussian beam, when it is propagating along the waveguide in the same direction of the c axis. This effect opens new applications of photorefractive waveguides in integrated optics. These characteristics can be exploited for steering of light beams in a waveguide.
