Spatial rogue waves in photorefractive SBN crystals
C. Hermann-Avigliano, I. A. Salinas, D. A. Rivas +5
We report on the excitation of large-amplitude waves, with a probability of around 1% of total peaks, on a photorefractive SBN crystal by using a simple experimental setup at room…
Compactification tuning for nonlinear localized modes in sawtooth lattices
Magnus Johansson, Uta Naether, Rodrigo A. Vicencio
We discuss the properties of nonlinear localized modes in sawtooth lattices, in the framework of a discrete nonlinear Schrödinger model with general on-site nonlinearity. Analytic…
Mobility of solitons in one-dimensional lattices with the cubic-quintic nonlinearity
C. Mejía-Cortés, Rodrigo A. Vicencio, Boris A. Malomed
We investigate mobility regimes for localized modes in the discrete nonlinear Schrödinger (DNLS) equation with the cubic-quintic onsite terms. Using the variational approximation (…
Self-trapping threshold in disordered nonlinear photonic lattices
U. Naether, M. Heinrich, Y. Lahini +4
We investigate numerically and experimentally the influence of coupling disorder on the self-trapping dynamics in nonlinear one-dimensional optical waveguide arrays. The existence…
Discrete flat-band solitons in the Kagome lattice
Rodrigo A. Vicencio, Magnus Johansson
We consider a model for a two-dimensional Kagome-lattice with defocusing nonlinearity, and show that families of localized discrete solitons may bifurcate from localized linear mod…
Self-trapping transition in nonlinear cubic lattices
Uta Naether, Alejandro J. Martínez, Diego Guzmán-Silva +2
We explore the fundamental question of the critical nonlinearity value needed to dynamically localize energy in discrete nonlinear cubic (Kerr) lattices. We focus on the effective…
