“…While the potential of tailored light fields, especially Airy beams, is well recognized in these fields, they are also of significant importance for advances in discrete and nonlinear modern photonics. On the one hand, the influence of inhomogeneous refractive index potentials on Airy beams has been investigated theoretically to design the beam caustics [10][11][12], on the other hand it was experimentally demonstrated that a linear refractive index gradient or a photonic lattice can be used to control and compensate the Airy beam self-acceleration [13][14][15]. Another inventive idea shifts the perspective and uses two-dimensional Airy beams itself to optically induce light guiding structures for optical routing and switching of signals [16].…”

We demonstrate a new type of soliton formation arising from the interaction of multiple two-dimensional Airy beams in a nonlinear medium. While in linear regime, interference effects of two or four spatially displaced Airy beams lead to accelerated intensity structures that can be used for optical induction of novel light guiding refractive index structures, the nonlinear cross-interaction between the Airy beams decelerates their bending and enables the formation of straight propagating solitary states. Our experimental results represent an intriguing combination of two fundamental effects, accelerated optical beams and nonlinearity, together enable novel mechanisms of soliton formation that will find applications in all-optical light localization and switching architectures. Our experimental results are supported by corresponding numerical simulations.

“…By studying further the impact of the nonlinearity of the medium on the propagation of an Airy beam, various theoretical as well as experimental studies have demonstrated that the shape and trajectory and therefore the acceleration of the Airy beam can be engineered via a refractive index variation 5 6 7 . The control of the Airy beam’s ballistic properties using either the medium nonlinearity or photonic lattices 8 9 offers new possibilities in all-optical waveguiding or routing.…”

The unique bending and shape-preserving properties of optical Airy beams offer a large range of applications in for example beam routing, optical waveguiding, particle manipulation and plasmonics. In these applications and others, the Airy beam may experience nonlinear light-matter interactions which in turn modify the Airy beam properties and propagation. A well-known example is light self-focusing that leads to the formation of spatial soliton. Here, we unveil experimentally the self-focusing properties of a 1D-Airy beam in a photorefractive crystal under focusing conditions. The transient evolution involves both self-bending and acceleration of the initially launched Airy beam due to the onset of an off-shooting soliton and the resulting nonlocal refractive index perturbation. Both the transient and stationary self-focusing properties can be tuned by varying the bias electric field, the injected Airy beam power and the background illumination.

“…In the past few years, Airy beam has been extensively studied in different media, including optically linear [5,10] and nonlinear medium [11][12][13][14], chiral media [15], photonic lattices [16], and so on. Atomic vapor is a good platform for studying the generation, propagation and manipulation of optical beams as its optical properties are well known for us.…”
