As the formation of spatial optical solitons in photorefractive media is governed by modification of the refractive index every single solitons in complex configurations of solitons can act as a single waveguide for other light beams. In this article

Large two-dimensional spatial soliton arrays are generated experimentally and numerically in photorefractive media and their waveguiding properties at red and infrared wavelengths are demonstrated. An enhanced stability of solitonic lattices is achie

We report on the stabilization of inherently unstable counterpropagating photorefractive spatial solitons by the use of one- and two-dimensional photonic lattices. We numerically investigate the dependence of the instability dynamics on period and am

We generate experimentally different types of two-dimensional self-trapped photonic lattices in a photorefractive medium and analyze the induced refractive index change using two different methods. One method gives the first experimental Fourier spac

This paper presents experimental results of two counterpropagating (2+1)D solitary beams propagating inside a photorefractive strontium-barium-niobate (SBN) crystal. Non-transient dynamical behaviour is observed and experimental evidence for a numeri

We study theoretically and investigate experimentally nonlinear photonic lattices of different symmetries generated by pixel-like solitons in a photorefractive medium. The light-induced periodically modulated nonlinear refractive index is highly anis

We review the propagation and interaction behavior of spatial screening solitons generated in a photorefractive SBN crystal in order to exploit them for new perspectives in soliton-driven photonics. We report on the successful experimental generation
