Nonlocal stabilization of nonlinear beams in a self-focusing atomic vapor

S. Skupin, M. Saffman, W. Krolikowski

We show that ballistic transport of optically excited atoms in an atomic vapor provides a nonlocal nonlinearity which stabilizes the propagation of vortex beams and higher order mo…

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…

Tamm states in one dimensional photonic crystals containing left-handed materials

Abdolrahman Namdar

We present a theoretical study of electromagnetic surface waves localized at an interface separating a conventional uniform medium and a semi-infinite 1-D photonic crystal made of…

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…
