Solitonic lattices in photorefractive crystals
Two-dimensional spatial solitonic lattices are generated and investigated experimentally and numerically in an SBN:Ce crystal. An enhanced stability of these lattices is achieved by exploiting the anisotropy of coherent soliton interaction, in particular the relative phase between soliton rows. Manipulation of individual soliton channels is achieved by use of supplementary control beams.
