Demonstration of all-optical beam steering in modulated photonic lattices
Christian R. Rosberg, Ivan L. Garanovich, Andrey A. Sukhorukov +3
We demonstrate experimentally all-optical beam steering in modulated photonic lattices induced optically by three beam interference in a biased photorefractive crystal. We identify…
Enhanced parametric processes in binary metamaterials
Maxim V. Gorkunov, Ilya V. Shadrivov, Yuri S. Kivshar
We suggest double-resonant (binary) metamaterials composed of two types of magnetic resonant elements, and demonstrate that in the nonlinear regime such metamaterials provide uniqu…
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…
Focusing and correlation properties of white-light optical vortices
Vladlen Shvedov, Wieslaw Krolikowski, Alexander Volyar +3
We generate double-charge white-light optical vortices by sending a circularly polarized partially incoherent light through an uniaxial crystal. We show that the generated polichro…
Soliton control in modulated optically-induced photonic lattices
Ivan L. Garanovich, Andrey A. Sukhorukov, Yuri S. Kivshar
We discuss soliton control in reconfigurable optically-induced photonic lattices created by three interfering beams. We reveal novel dynamical regimes for strongly localized solito…
Second-harmonic generation in nonlinear left-handed metamaterials
Ilya V. Shadrivov, Alexander A. Zharov, Yuri S. Kivshar
We study the second-harmonic generation in left-handed metamaterials with a quadratic nonlinear response. We demonstrate a novel type of the exact phase matching between the backwa…
