“…In order to extract a measure for the disorder strength as a function of the illumination time we employ the technique of waveguiding [32]. Thus, during the illumination sequence we send a plane wave onto the random potential landscape of particular contrast and record the intensity distribution at the back face of the crystal.…”

We present a method to demonstrate Anderson localization in an optically induced randomized potential. By usage of computer controlled spatial light modulators, we are able to implement fully randomized nondiffracting beams of variable structural size in order to control the modulation length (photonic grain size) as well as the depth (disorder strength) of a random potential induced in a photorefractive crystal. In particular, we quantitatively analyze the localization length of light depending on these two parameters and find that they are crucial influencing factors on the propagation behavior leading to variably strong localization. Thus, we corroborate that transverse light localization in a random refractive index landscape strongly depends on the character of the potential, allowing for a flexible regulation of the localization strength by adapting the optical induction configuration.

We present a progress overview focused on the recent theoretical and experimental advances in the area of soliton manipulation in optical lattices. Optical lattices offer the possibility to engineer and to control the diffraction of light beams in media with periodicallymodulated optical properties, to manage the corresponding reflection and transmission bands, and to form specially designed defects. Consequently, they afford the existence of a rich variety of new families of nonlinear stationary waves and solitons, lead to new rich dynamical phenomena, and offer novel conceptual opportunities for all-optical shaping, switching and routing of optical signals encoded in soliton formats. In this overview, we consider reconfigurable optically-induced lattices as well as waveguide arrays made in suitable nonlinear materials. We address both, one-dimensional and multi-dimensional geometries.We specially target the new possibilities made possible by optical lattices induced by a variety of existing non-diffracting light patterns, we address nonlinear lattices and soliton arrays, and we briefly explore the unique features exhibited by light propagation in defect modes and in random lattices, an area of current topical interest and of potential crossdisciplinary impact.

“…To experimentally realize the photonic lattices for controlling the acceleration of the Airy beam we use the technique of optical induction [20], which in the past has proved its flexibility to create various types of two-and three-dimensional photonic lattices [24][25][26]. Moreover, this approach provides a versatile platform to study different fundamental linear and nonlinear propagation effects, such as Anderson localization [27] or discrete lattice and vortex solitons [28,29].…”

We demonstrate control over the acceleration of two-dimensional Airy beams propagating in optically induced photonic lattices. Depending on the lattice strength, we observe a slowing-down and suppression of the selfacceleration of Airy beams, as well as a formation of discrete lattice beams. Moreover, we explore the effects of different artificial single-side defects on the propagation and acceleration. For positive defects, the localization of the Airy beam to the defect site is further enhanced, while for negative defects most of the power is repelled from this site.
