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 …

Structured light refers to the arbitrarily tailoring of optical fields in all their degrees of freedom
(DoFs), from spatial to temporal. Although orbital angular momentum (OAM) is perhaps the …

Over the past few decades, there has been extensive research work carried out in the area
of nonlinear optics and opened a myriad of applications in material science and …

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 …

We investigate the nonlinear mixing of orbital angular momentum in type-II second-harmonic
generation with arbitrary topological charges imprinted on two orthogonally polarized …

We present a high beam quality, mid-infrared, wavelength tunable, idler-resonant optical
vortex parametric oscillator based on a single-grating MgO-doped periodically poled lithium …

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 …

It is possible to prepare classical optical beams which cannot be characterized by a tensor
product of vectors describing each of their degrees of freedom. Here we report the …
