Beam splitter and combiner based on Bloch oscillations in spatially modulated waveguide arrays
Yiqi Zhang, Milivoj R. Belić, Weiping Zhong +5
We numerically investigate the light beam propagation in periodic waveguide arrays which are elaborately modulated with certain structures. We find that the light beam may split, c…
Two-dimensional linear and nonlinear Talbot effect from rogue waves
Yiqi Zhang, Milivoj R. Belić, Milan S. Petrović +5
We introduce two-dimensional (2D) linear and nonlinear Talbot effects. They are produced by propagating periodic 2D diffraction patterns and can be visualized as 3D stacks of Talbo…
Fresnel diffraction patterns as accelerating beams
Yiqi Zhang, Milivoj R. Belić, Huaibin Zheng +4
We demonstrate that beams originating from Fresnel diffraction patterns are self-accelerating in free space. In addition to accelerating and self-healing, they also exhibit parabol…
Soliton pair generation in the interactions of Airy and nonlinear accelerating beams
Yiqi Zhang, Milivoj Belić, Zhenkun Wu +4
We investigate numerically the interactions of two in-phase and out-of-phase Airy beams and nonlinear accelerating beams in Kerr and saturable nonlinear media, in one transverse di…
Multicharged optical vortices induced in a dissipative atomic vapor system
Yiqi Zhang, Milivoj R. Belic, Zhenkun Wu +4
We investigate numerically the dynamics of optical vortex beams carrying different topological charges, launched in a dissipative three level ladder type nonlinear atomic vapor. We…
Optical vortices induced in nonlinear multilevel atomic vapors
Yiqi Zhang, Zhenkun Wu, Chenzhi Yuan +4
In a numerical investigation, we demonstrate the existence and curious evolution of vortices in a ladder-type three-level nonlinear atomic vapor with linear, cubic, and quintic sus…
