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…
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…
Vectorial structure of a hard-edged-diffracted four-petal Gaussian beam in the far field
Xuewen Long, Keqing Lu, Yuhong Zhang +2
Based on the vector angular spectrum method and the stationary phase method and the fact that a circular aperture function can be expanded into a finite sum of complex Gaussian fun…
Analytical vectorial structure of non-paraxial four-petal Gaussian beams in the far field
Xuewen Long, Keqing Lu, Yuhong Zhang +2
The analytical vectorial structure of non-paraxial four-petal Gaussian beams(FPGBs) in the far field has been studied based on vector angular spectrum method and stationary phase m…
