We demonstrate both theoretically and experimentally that photonic lattices under self-defocusing nonlinearity support gap solitons in various shapes such as cross and H shapes. These solitons, with their intensity humps all in-phase, are stable against perturbations, thus they propagate robustly throughout the lattices. Based on this finding, we propose(More)
We generate optical beams with rotating intensity blades, namely “optical propellers”, by employing Moiré technique. Such rotating beams are controlled by SLM without mechanical movement or phase-sensitive interference. Self-trapping of propelling beams is also demonstrated.
