Nonlinear Bloch-wave interaction and Bragg scattering in optically-induced lattices
arXiv:nlin/0309075 · doi:10.1103/PhysRevLett.92.093901
Abstract
We study, both theoretically and experimentally, the Bragg scattering of light in optically-induced photonic lattices and reveal the key physical mechanisms which govern nonlinear self-action of narrow beams under the combined effects of Bragg scattering and wave diffraction, allowing for selecting bands with different effective dispersion.
