Controlled generation and steering of spatial gap solitons
Dragomir Neshev, Andrey A. Sukhorukov, Brendan Hanna +2
We demonstrate the first fully controlled generation of immobile and slow spatial gap solitons in nonlinear periodic systems with band-gap spectra, and reveal the key features of g…
Nonlinear Bloch-wave interaction and Bragg scattering in optically-induced lattices
Andrey A. Sukhorukov, Dragomir Neshev, Wieslaw Krolikowski +1
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…
Observation of transverse instabilities in optically-induced lattices
Dragomir Neshev, Andrey A. Sukhorukov, Yuri S. Kivshar +1
We study experimentally the Bloch-wave instabilities in optically-induced lattices. We reveal two different instability scenarios associated with either the transverse modulational…
Multi-gap discrete vector solitons
Andrey A. Sukhorukov, Yuri S. Kivshar
We analyze nonlinear collective effects in periodic systems with multi-gap transmission spectra such as light in waveguide arrays or Bose-Einstein condensates in optical lattices.…
