Polarization properties of fanning light in fiberlike bismuth titanium oxide crystals.
We demonstrate that the fanning light emerging from an optically active fiberlike bismuth titanium oxide (Bi(12)TiO(20)) crystal is linearly polarized either parallel to the applied electric-field vector or perpendicular to it, independently of the external ac electric field, the crystal length, and the pump beam polarization state. We show also that a photorefractive surface wave can be generated at the opposite crystal sides, depending on the pump beam polarization.
