Talbot effect in nonparaxial self-accelerating beams with electromagnetically induced transparency
Jingmin Ru, Zhenkun Wu, Yagang Zhang +2
In this study, we report on the fractional Talbot effect of nonparaxial self-accelerating beams in a multilevel electromagnetically induced transparency (EIT) atomic configuration,…
Modulation of the photonic band structure topology of a honeycomb lattice in an atomic vapor
Yiqi Zhang, Xing Liu, Milivoj R. Belić +2
In an atomic vapor, a honeycomb lattice can be constructed by utilizing the three-beam interference method. In the method, the interference of the three beams splits the dressed en…
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…
Controlling multi-wave mixing signals via photonic band gap of electromagnetically induced absorption grating in atomic media
Yiqi Zhang, Zhenkun Wu, Xin Yao +4
We experimentally demonstrate dressed multi-wave mixing (MWM) and the reflection of the probe beam due to electromagnetically induced absorption (EIA) grating can coexist in a five…
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…
