Controlling the various degrees‐of‐freedom (DoFs) of structured light at both quantum and
classical levels is of paramount importance in optics. It is a conventional paradigm to treat …

The interest in tailoring light in all its degrees of freedom is steadily gaining traction, driven
by the tremendous developments in the toolkit for the creation, control and detection of what …

Optical angular momentum-based photonic technologies demonstrate the key role of the
optical spin–orbit interaction that usually refers to linear optical processes in spatially …

We demonstrate the spin to orbital angular momentum transfer in frequency upconversion
with structured light beams. A vector vortex is coupled to a circularly polarized Gaussian …

Tunable generation of vortex beams holds relevance in various fields, including
communications and sensing. In this paper, we demonstrate the feasibility of nonlinear spin …

Preparation, control, and measurement of optical vortices are increasingly important, as they
play essential roles in both fundamental science and optical technology applications. Spatial …

In this work we study the evolution of an optical vortex undergoing self-phase modulation
inside a nonlinear Kerr medium. The intensity-dependent phase evolution couples the …

Optical orbital angular momentum transformation and corresponding azimuthal-mode
selection rules have been studied exhaustively for various nonlinear optical interactions …

In this article we investigate the connection between the chirality of interacting vortices and
the appearance of radial structures in nonlinear wave mixing. Depending on the signs of …

The possibility of achieving and controlling scalable classically entangled, ie, inseparable,
multipartite states, would fundamentally challenge the advantages of quantum systems in …
