Nonlinear directional coupler for polychromatic light
Ivan L. Garanovich, Andrey A. Sukhorukov
We demonstrate that nonlinear directional coupler with special bending of waveguide axes can be used for all-optical switching of polychromatic light with very broad spectrum cover…
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…
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…
Slow-light optical bullets in arrays of nonlinear Bragg-grating waveguides
Andrey A. Sukhorukov, Yuri S. Kivshar
We demonstrate how to control independently both spatial and temporal dynamics of slow light. We reveal that specially designed nonlinear waveguide arrays with phase-shifted Bragg…
Self-trapping of polychromatic light in nonlinear photonic lattices
Kristian Motzek, Andrey A. Sukhorukov, Yuri S. Kivshar
We study dynamical reshaping of polychromatic beams due to collective nonlinear self-action of multiple-frequency components in periodic photonic lattices and predict the formation…
Surface multi-gap vector solitons
Ivan L. Garanovich, Andrey A. Sukhorukov, Yuri S. Kivshar +1
We analyze nonlinear collective effects near surfaces of semi-infinite periodic systems with multi-gap transmission spectra and introduce a novel concept of multi-gap surface solit…
Nonlinear Bloch modes in two-dimensional photonic lattices
Denis Traeger, Robert Fischer, Dragomir N. Neshev +4
We generate experimentally different types of two-dimensional Bloch waves of a square photonic lattice by employing the phase imprinting technique. We probe the local dispersion of…
