Controlled generation and steering of spatial gap solitons

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


We demonstrate the first fully controlled generation of immobile and slow spatial gap solitons in nonlinear periodic systems with band-gap spectra, and observe the key features of gap solitons that distinguish them from discrete solitons, including a dynamical transformation of gap solitons due to nonlinear interband coupling.We also describe theoretically and confirm experimentally the effect of the anomalous steering of gap solitons in optically induced photonic lattices.
