Abstract

We study interaction of a discrete vortex with a supporting photonic lattice and analyze how the combined action of the lattice periodicity and the medium nonlinearity can modify the vortex structure. In particular, we describe theoretically and observe in experiment, for the first time to our knowledge, the nontrivial topological transformations of the discrete vortex including the flipping of vortex charge and inversion of its orbital angular momentum. We also demonstrate the stabilizing effect of the interaction with the so-called “mixed” optically-induced photonic lattices on the vortex propagation and topological structure.

Comparison between the structural and topological instabilities of optical vortices. (a) Linearly unstable vortex soliton in a saturable bulk medium. (b) Generation of a stable vortex soliton on a square photonic lattice. (c) Topological transformations of the asymmetrically perturbed discrete vortex on the lattice [movie IsoUnfoldings.avi, 2.2MB]. The isosurfaces are plotted at the half-peak intensity (green) and at a small value ~ 10-2 (red). The red “string” in (b) shows the position of the vortex core, while bursts in (a) and (c) indicate the vortex unfoldings. (d) Dynamics of the angular momentum (normalized by the power) for all three cases.

Experimental setup: λ/2 - half-wave plate, PBS - polarising beam splitter, L - lenses, D - rotating diffuser, AM - amplitude mask of square array, FF - Fourier filtering of the four first diffraction orders, M - mirrors, BS - beam splitter, BSC - beam splitter cube, F - neutral density filter, SBN - Strontium Barium Niobate photorefractive crystal, and CCD - camera. Top left inset: schematic of the linear polarisation state of the lattice wave, forming its flexible and fixed components.

Topological transformation of an off-site vortex in a fixed lattice (induced by an ordinary polarized lattice wave). Upper row - intensity distribution; bottom row - phase interferogram. (a) Input vortex in the lattice; (b) linear diffraction; (c) nonlinear output with a transformed phase structure. (d) corresponding numerical simulations confirming the nonlinear phase transformation [movie FixedOFF.avi, 6.2MB]. Arrows and circles indicate the position of the vortex dislocations. The total charge of the beam in (c) is -1, i.e., it is inverted with respect to the initial charge +1.

Topological transformations of an on-site vortex in a mixed lattice with 3% nonlinear component. Upper row – intensity distribution; bottom row – phase interferograms. (a) Input vortex; (b) linear diffraction; (c) nonlinear output with a transformed phase structure; (d) corresponding numerical simulations [movie Mixed3ON.avi (2MB), see the description in the text]. Arrows and circles indicate the position of the vortex dislocations. Dotted oval indicates two closely positioned vortices with the opposite charges. The total beam charge in (c) is +1, i.e., it is preserved with respect to the initial charge +1. [Media 7

Fig. 5.

Topological transformation of the off-site vortex on a square flexible lattice. Trajectories of vortices are shown vs. lattice depth (relaxation time t after blocking the lattice beam at t = 0). The red lines (gray projections) correspond to vortex dislocation of charge +1, while the blue lines (black projections) correspond to charge -1.

Dynamics of the angular momentum for an off-site vortex interacting with a flexible lattice (black), fixed lattice (blue), and mixed (50/50%) photonic lattice (red). The black line is terminated when the flexible lattice loses its symmetry during interaction.
