Head-on excitation of tilted solitons by fragmented Bessel beams - Control and manipulation of light in complex photonic systems (CompsLight)

Experimental and numerical data correspond to the results reported in the journal paper published in Chaos, Solitons & Fractals, Vol. 202, Issue 1, pp. 117434 (2026) (https://doi.org/10.1016/j.chaos.2025.117434). The experimental data consist of original results in .png format, showing the intensity distributions of the Bessel beam after propagation through a 2 cm long cerium-doped strontium barium niobate (SBN61:Ce) crystal, recorded at the crystal output face. The numerical data include intensity distributions along the propagation distance in the crystal (i1a), where the final matrix of i1a corresponds to the experimental intensity pattern. The data are provided as Matlab .m files and include information about the numerical space in micrometers (x, y) and in millimeters (z). Sxa and Sya denote the x- and y-components of the Poynting vector, respectively.
