  • Title: Spatial solitons in nematic liquid crystals: from bulk to discrete.
    Author: Assanto G, Fratalocchi A, Peccianti M.
    Journal: Opt Express; 2007 Apr 16; 15(8):5248-59. PubMed ID: 19532777.
    Abstract:
    We review theoretical and experimental results on spatial solitons in nematic liquid crystalline cells, including two-dimensional solitons in bulk and discrete solitons in one-dimensional waveguide arrays. In bulk we describe the propagation of continuous solitons in the presence of adjustable walk-off, their interaction with light-induced defects and refraction-reflection at a voltage-tunable interface. In optical lattices we address the transition from discrete diffraction to localization, as well as all-optical beam steering.
