Reduced-symmetry two-dimensional solitons in photonic lattices
Robert Fischer, Denis Traeger, Dragomir N. Neshev +4
We demonstrate theoretically and experimentally a novel type of localized beams supported by the combined effects of total internal and Bragg reflection in nonlinear two-dimensiona…
Wave scattering by metamaterial wedges and interfaces
Andrey A. Sukhorukov, Ilya V. Shadrivov, Yuri S. Kivshar
We outline specific features of numerical simulations of metamaterial wedges and interfaces. We study the effect of different positioning of a grid in the Yee method, which is nece…
Soliton dynamics in deformable nonlinear lattices
Andrey A. Sukhorukov
We describe wave propagation and soliton localization in photonic lattices which are induced in a nonlinear medium by an optical interference pattern, taking into account the inher…
Enhanced soliton transport in quasi-periodic lattices with short-range aperiodicity
Andrey A. Sukhorukov
We study linear transmission and nonlinear soliton transport through quasi-periodic structures, which profiles are described by multiple modulation frequencies. We show that resona…
Engineering Fano resonances in discrete networks
Andrey E. Miroshnichenko, Yuri S. Kivshar
We study transmission properties of discrete networks composed of linear arrays coupled to systems of N side defects, and demonstrate the basic principles of the resonant scatterin…
Incoherent multi-gap optical solitons in nonlinear photonic lattices
Kristian Motzek, Andrey A. Sukhorukov, Friedemann Kaiser +1
We demonstrate numerically that partially incoherent light can be trapped in the spectral band gaps of a photonic lattice, creating partially incoherent multi-component spatial opt…
