Two dimensional Airy beam soliton

We demonstrate the formation of a two dimensional Airy beam soliton in a photorefractive crystal. By simply varying the nonlinearity strength we identify several scenarios showing the coexistence between an Airy beam and the emerging soliton. The soliton output profile behaves according to the theoretical soliton existence curve and can be tailored by the nonlinearity strength even without modifying the input Airy beam shape. This last feature makes this Airy soliton distinct from the Gaussian beam generated photorefractive soliton.

Automated summary

In this study, we demonstrate the formation of a two-dimensional Airy beam soliton in a photorefractive crystal. By varying the nonlinearity strength, we observe the coexistence between an Airy beam and the emerging soliton. The soliton's output profile follows the theoretical soliton existence curve and can be tailored by the nonlinearity strength, even without modifying the input Airy beam shape. This feature distinguishes the Airy soliton from the Gaussian beam generated photorefractive soliton.
