Discrete interband mutual focusing in nonlinear photonic lattices

Rosberg, Christian; Hanna, Brendan; Neshev, Dragomir; Krolikowski, Wieslaw; Sukhorukov, Andrey; Kivshar, Yuri

Description

We study nonlinear coupling of mutually incoherent beams associated with different Floquet-Bloch waves in a one-dimensional optically-induced photonic lattice. We demonstrate experimentally how such interactions lead to asymmetric mutual focusing and, for waves with opposite diffraction properties, to simultaneous focusing and defocusing as well as discreteness-induced beam localization and reshaping effects.
