Paper Abstract

Dynamic holographic gratings can be used in optical waveguides on photorefractive electro- optical crystals for an information input in integrated-optical algebraic processors. An influence of the Fe and Cu additional diffusion on the refractive index profile and photorefractive properties of LiNbO3:Ti waveguides has been investigated and two possible schemes for dynamic holographic element formation at the single input light beam have been proposed. Holographic grating recording at photorefractive parametric interaction of radiation and waveguide modes is used in the first of them and formation of such grating while light diffraction at counter propagating and a little tilted surface acoustic wave beams -- in the second one.
