We investigated the light-induced backward scattering in doubly doped lithium niobate crystals and observed an intensity threshold effect. It will be shown that scattering microregions are locally recorded in the sample by holographic interaction due to the existence of the threshold effect. Experimental results of multilayer recording point out that this property could be used for high-density multilayer-like bit data optical storage while keeping high signal-to-noise ratio.

    We describe a technique for surface domain engineering in congruent lithium niobate single crystals. The method is based on conventional electric-field poling, but involves an intentional overpoling step that inverts all the material apart from a thin surface region directly below the patterned...

    Transmission electron microscope studies of Ti-doped, congruent lithium niobate (LiNbO3) have shown that extended structural faults are only present within the Ti-diffused layer (i.e., the wave guiding region). Structural faults have also been observed in undoped Li-deficient LiNbO3, though not...

    We have found that in connection with photorefraction the Li-rich LiNbo3:Mg (5 mol %) can withstand higher light intensities than the congruent LiNbO3:Mg (5 mol %) and that the improvement is due to the increased photoconductivity with little change in photovoltaic current.

    Proton-exchanged optical waveguides in lithium niobate crystals exhibit a rich variety of structures and phases.

    Periodically poled lithium niobate crystals doped with transition-metal ions Cr[sup 3+] and Hf[sup 4+], and rare earth ions Er[sup 3+] and Yb[sup 3+] were grown by the Czochralski method.
