“…Different types of spatiotemporal self-accelerating wave packets in SNNM are also studied. The numerical simulation findings consistent with their theoretical findings in the strongly nonlocal requirement, and the numerical simulation under different perturbation conditions is discussed [23,24].…”

In the ABCD optical system, the propagation properties and the radiation forces are obtained by studying the cross spectral density of partially coherent self-shifting cosine-Gaussian beams. A self-shifting phenomenon occurs when the beams propagate in the strongly nonlocal nonlinear medium. The shifting parameters could influence the bend characteristics of the propagation trajectory and the beam center, while the power ratio affects the periods of the parabolic trajectory. Furthermore, the radiation forces on a Rayleigh particle in the focusing optical system are studied, and the obtained force distributions depend on the refractive index, the shifting parameters, and the coherence widths. What we report here has potential applications in optical communication and optical tweezing.

“…Furthermore, considerable attention has also been paid to the propagation of non-diffracting beams in the diverse mediums, such as gradient-index medium [16,18], chiral media [19], strongly nonlocal nonlinear media [20][21][22], etc, in which the chiral media, is known to contain mirror asymmetric components, can separate linearly polarized light into two circular polarization [23]: left circular polarization (LCP) and right circular polarization (RCP). The chiral medium has unique features and remarkable impacts on the propagation of laser beams as compared to conventional substances.…”

Lommel beams have significant applications in optical communication and optical manipulation due to the changeable symmetry of transverse intensity distribution and constantly varying orbital angular momentum. In this paper, a novel quasi-diffraction-free Lommel-Airy vortex (LAiV) wavepackets is proposed, and spatiotemporal dynamics of the LAiV wavepackets propagating in chiral media are investigated. Results indicate that several variables such as topological charge , group velocity , asymmetry factor , and chiral parameter could be used to regulate the profiles of the 3D spatiotemporal vortex rings. Particularly, the spatiotemporal propagation trajectories and intensity patterns of the LAiV wavepackets could be manipulated by altering the asymmetry factor and the chiral parameter . These results would deepen the understanding of the spatiotemporal propagation properties of the LAiV wavepackets and are expected to promote the development of the novel optical communications in chiral media.
