In case of the anisotropic self-diffraction process the polarization of diffracted beam will be rotated by some angle with respect to the transmitted object beam polarization. This happens in photorefractive crystals like BSO/BTO when the input face of the crystal is [110] plane and hologram vector coincides with [110] axis[30] and is shown in Fig 4.3. In this geometry when both object and reference beams interfere in the photorefractive (Bismuth Silicon Oxide), the amplitude of the phase grating produced inside the crystal is a maximum for light linearly polarized along and perpendicular to an axis bisecting the [001] and [110] crystal axes (i.e., at 450 to the grating vector Kg). This occurs due to the ...
