Soliton control and bloch-wave filtering in periodic photonic lattices.

چکیده
We suggest a novel approach to soliton control and routing based on Bloch-wave filtering in periodic photonic structures. Taking a binary waveguide array as an example, we demonstrate that spatial solitons that belong to different spectral gaps can be selectively reflected from or transmitted through an engineered defect, which acts as a low- or high-pass filter for Bloch waves.

Soliton switching and Bloch-wave filtering in periodic photonic lattices
The study of nonlinear light propagation in periodic photonic structures recently attracted strong interest because it presents the unique possibility of observing experimentally an interplay between the effects of nonlinearity and periodicity. Fabricated nonlinear periodic structures such as arrays of coupled nonlinear optical waveguides can simultaneously support distinctive types of self-tra...
متن کاملSoliton control in chirped photonic lattices
We study optical solitons in chirped periodic optical lattices whose amplitude or frequency changes in the transverse direction. We discover that soliton propagation in such lattices can be accompanied by the progressive self-bending of the soliton trajectory, and we show that the soliton bending rate and output position can be controlled by varying the lattice depth, as well as the chirp ampli...
متن کاملLight propagation and localization in modulated photonic lattices and waveguides
We review both theoretical and experimental advances in the recently emerged field of modulated photonic lattices. These artificial periodic dielectric structures provide a powerful tool for the control of the fundamental aspects of light propagation. Photonic lattices are arrays of coupled optical waveguides, where the light propagation becomes effectively discretized. The discretized nature o...

We discuss soliton control in reconfigurable optically-induced photonic lattices created by three interfering beams. We reveal novel dynamical regimes for strongly localized solitons, including binary switching and soliton revivals through resonant wave mixing.

We analyze the Floquet-Bloch matter-wave spectrum of Bose-Einstein condensates loaded into single-periodic optical lattices and double-periodic superlattices. In the framework of the Gross-Pitaevskii equation, we describe the structure and analyze the mobility properties of dark matter-wave solitons residing on the background of extended nonlinear Bloch-type states. We demonstrate that interact...
