Slow-light switching in nonlinear Bragg-grating coupler
Sangwoo Ha, Andrey A. Sukhorukov, Yuri S. Kivshar
We study propagation and switching of slow-light pulses in nonlinear couplers with phase-shifted Bragg gratings. We demonstrate that power-controlled nonlinear self-action of light…
Simple and efficient generation of gap solitons in Bose-Einstein condensates
Michal Matuszewski, Wieslaw Krolikowski, Marek Trippenbach +1
We suggest an efficient method for generating matter-wave gap solitons in a repulsive Bose-Einstein condensate, when the gap soliton is formed from a condensate cloud in a harmonic…
Polychromatic interface solitons in nonlinear photonic lattices
Kristian Motzek, Andrey A. Sukhorukov, Yuri S. Kivshar
We demonstrate that interfaces between two nonlinear periodic photonic lattices offer unique possibilities for controlling nonlinear interaction between different spectral componen…
Tunable split-ring resonators for nonlinear negative-index metamaterials
Ilya V. Shadrivov, Steven K. Morrison, Yuri S. Kivshar
We study experimentally the dynamic tunability and self-induced nonlinearity of split-ring resonators incorporating variable capacitance diodes. We demonstrate that the eigenfreque…
Broadband diffraction management and self-collimation of white light in photonic lattices
Ivan L. Garanovich, Andrey A. Sukhorukov, Yuri S. Kivshar
We suggest a novel type of photonic structures where the strength of diffraction can be managed in a very broad frequency range. We introduce optimized arrays of curved waveguides…
Melting of Discrete Vortices via Quantum Fluctuations
Chaohong Lee, Tristram J. Alexander, Yuri S. Kivshar
We consider nonlinear boson states with a nontrivial phase structure in the three-site Bose-Hubbard ring, {\em quantum discrete vortices} (or {\em q-vortices}), and study their "me…
