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…
Self-Fourier transform and self-Fourier beams due to parabolic potential
Yiqi Zhang, Xing Liu, Milivoj R. Belić +3
We investigate the propagation of light beams including Hermite-Gauss, Bessel-Gauss and finite energy Airy beams in a linear medium with parabolic potential. Expectedly, the beams…
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…
Photonic Floquet Topological Insulator in an Atomic Ensemble
Yiqi Zhang, Zhenkun Wu, Milivoj R. Belić +4
We demonstrate the photonic Floquet topological insulator (PFTI) in an atomic vapor with nonlinear susceptibilities. The interference of three coupling fields splits the energy lev…
Interactions of incoherent localized beams in a photorefractive medium
Yiqi Zhang, Milivoj R. Belić, Huaibin Zheng +4
We investigate numerically interactions between two bright or dark incoherent localized beams in an strontium barium niobate photorefractive crystal in one dimension, using the coh…
Three-dimensional nonparaxial accelerating beams from the transverse Whittaker integral
Yiqi Zhang, Milivoj R. Belić, Huaibin Zheng +4
We investigate three-dimensional nonparaxial linear accelerating beams arising from the transverse Whittaker integral. They include different Mathieu, Weber, and Fresnel beams, amo…
Interactions of Airy beams, nonlinear accelerating beams, and induced solitons in Kerr and saturable nonlinear media
Yiqi Zhang, Milivoj R. Belić, Huaibin Zheng +4
We investigate numerically interactions between two in-phase or out-of-phase Airy beams and nonlinear accelerating beams in Kerr and saturable nonlinear media in one transverse dim…
The Nonlinear Talbot Effect of Rogue Waves
Yiqi Zhang, Milivoj R. Belić, Huaibin Zheng +4
Akhmediev and Kuznetsov-Ma breathers are rogue wave solutions of the nonlinear Schrödinger equation (NLSE). Talbot effect (TE) is an image recurrence phenomenon in the diffraction…
