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…
Complete bandgaps in one-dimensional left-handed periodic structures
Ilya V. Shadrivov, Andrey A. Sukhorukov, Yuri S. Kivshar
Artificially fabricated structures with periodically modulated parameters such as photonic crystals offer novel ways of controlling the flow of light due to the existence of a rang…
Bistable diode action in left-handed periodic structures
Michael W. Feise, Ilya V. Shadrivov, Yuri S. Kivshar
We study nonlinear transmission of an asymmetric multilayer structure created by alternating slabs of two materials with positive and negative refractive index. We demonstrate that…
