  • Title: Spatial solitons and modulational instability in the presence of large birefringence: the case of highly nonlocal liquid crystals.
    Author: Conti C, Peccianti M, Assanto G.
    Journal: Phys Rev E Stat Nonlin Soft Matter Phys; 2005 Dec; 72(6 Pt 2):066614. PubMed ID: 16486085.
    Abstract:
    With reference to spatially nonlocal nematic liquid crystals, we develop a theory of optical spatial solitons and modulational instability in anisotropic media with arbitrarily large birefringence. Asymmetric spatial profiles and multivalued features are predicted for self-localized light versus walk-off angle. The results hold valid for generic self-focusing birefringent media and apply to large angle steering of individual and multiple self-trapped optical beams.
