Journal ArticleDOI
Soliton stripes in two-dimensional nonlinear photonic lattices.
TL;DR: A novel type of composite soliton created by strong coupling of mutually incoherent periodic and localized beam components is observed by imposing an initial transverse momentum on the soliton stripe by observing the effect of lattice compression and deformation.
Journal ArticleDOI
Multicolor solitons due to four-wave mixing
TL;DR: The structure and stability of different types of multicolor optical spatial solitary waves created by interaction of light at a central frequency with two sideband waves both through cross-phase modulation and parametric four-wave mixing is presented in this paper.
Journal ArticleDOI
A comparative analysis of surface and bulk contributions to second-harmonic generation in centrosymmetric nanoparticles
TL;DR: This study reveals that, whereas for plasmonic nanoparticles the surface contribution is always dominant, the bulk and surface SHG effects can become comparable for dielectric nanoparticles, and thus they both should be taken into account when analyzing nonlinear optical properties of all-dielectric nanostructures.
Journal ArticleDOI
Nonlinearity-induced conformational instability and dynamics of biopolymers

TL;DR: A simple phenomenological model for describing the conformational dynamics of biopolymers via the nonlinearity-induced buckling and collapse instability is proposed and its role in the folding dynamics of macromolecules is demonstrated through the three-dimensional numerical simulations of long semiflexible chains.
Journal ArticleDOI
Observation of bound states of interacting vector solitons.
TL;DR: Experimental observation of bound states formed by two well-separated vector spatial solitons as the result of a force balance between vector-soliton components and a link between such soliton bound states and two-hump, two-modesolitons is demonstrated.
