Vortex-induced rotating structures in optical photonic lattices
Abstract:
Rotational properties of counterpropagating mutually incoherent self-trapped vortex beams in optically induced fixed photonic lattices are investigated numerically. Different lattice structures are considered, such as hexagonal/trigonal and circular photonic lattices. Periodically increasing propagation distance, regular nonlocal rotation of vortex filaments is observed for hexagonal photonic lattice. For circular photonic lattices with negative defect, we discover novel types of rotating beam structures that have no counterparts in the case without the lattice. Observed rotating structures are stable in the presence of noise.
