Controlling the symmetry of optical and mechanical waves is pivotal to their full exploitation in technological applications and topology-linked fundamental physics experiments. Leveraging on the control of orbital angular momentum, we introduce here

We propose and numerically test a novel concept for asymmetric vortex beam generation in a Degenerate Vertical External Cavity Surface Emitting Laser (DVECSEL). The method is based on a phase-locking ring array of lasers created inside a degenerate c

An optical vortex beam propagating through turbulent atmosphere encounters distortions in the wavefront that results in modal scattering. Abruptly autofocussing (AAF) beams with orbital angular momentum have gained significant attention due to their

When microspheres are illuminated by tightly focused vortex beams, they can be trapped in a non-equilibrium steady state where they orbit around the optical axis. By using the Mie-Debye theory for optical tweezers, we demonstrate that the orbital per

Abstract Pulsed polarized vortex beams, a special form of structured light, are generated by tailoring the light beam spatiotemporally and witness the growing application demands in nonlinear optics such as ultrafast laser processing and surface plas

In free-space diffraction, the orbital angular momentum(OAM)of the vortex light field remains unchanged. However, in a turbulent layer, the symmetry of the OAM spectrum distribution will be broken, and the OAM will change due to the existence of a qu

Recently, meta-surface(MS) has emerged as a promising alternative method for generating vortex waves. At the same time, MS also face the problem of narrow bandwidth, in order to obtain a board bandwidth, the MS unit cells structure become more and mo
