Abstract
Abstract
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
n
,
group velocity
v
g
,
asymmetry factor
c
,
and chiral parameter
γ
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
c
and the chiral parameter
γ
.
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.
