Abstract

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 anisotropic and nonlocal, and it depends on the lattice orientation relative to the optical axis of the crystal. We discuss the stability of these induced photonic structures and their guiding properties.
