“…Optical modulation of the parameters of individual waveguide elements using focused light beams is also possible. The optical analog of the Anderson localization was obtained experimentally in this way in the initially periodic waveguide system on the surface of a LiNbO 3 wafer by Ti diffusion [48].…”

535.417Special features of spatial self-action of light fields in nonlinear optical photonic waveguide structures formed in strontium barium niobate and lithium niobate electro-optic crystals are discussed. The main methods of forming such structures including photorefractive waveguide elements and systems are briefly considered. The formation of spatial optical solitons in planar waveguides based on lithium niobate and strontium barium niobate crystals as well as in one-dimensional photonic lattices in lithium niobate is demonstrated experimentally for light beams of microwatt power. In regimes of spatial optical solitons, channel optical waveguides are formed not only in the planar waveguides, but also in the volume of photorefractive lithium niobate.

“…Following recent experimental observation of AL in a disordered twodimensional (2D) optically induced photonic lattice (PL) [8], AL of matter waves in a 1D disordered Bose-Einstein condensate (BEC) [9], and Anderson-like localization of light in a 1D PL with randomly distributed defects [10], the transverse localization of light as it propagates in disordered photonic crystals has become a hot topic of research.…”

We demonstrate Anderson localization of mutually incoherent counterpropagating beams in an optically induced two-dimensional photonic lattice. The effect is displayed in a system of two broad probe beams propagating head-on through a fixed disordered photonic lattice recorded in a photorefractive crystal. In addition to the steady-state localization, we also observe the dynamical localization; that is, the localization of time-changing beams. As compared to the localization of single beams, in which there exist no dynamical effects, the localization of counterpropagating beams is more pronounced and prone to instabilities.

“…One of the ways to form similar photonic elements in photorefractive crystals is optical inducing, which allows to set and manage different topologies during the formation of such structures [4,5]. The photorefractive sensitivity of lithium niobate (LiNbO 3 ), lithium tantalate (LiTaO 3 ), strontium-barium niobate (Sr Ba 1− Nb 2 O 6 ) and some other crystals can be changed by several orders of magnitude, varying the concentration of impurities introduced when samples are doped through the surface or during the growth of crystals [6,7].…”
