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 …

Research on spatially structured light has seen an explosion in activity over the past
decades, powered by technological advances for generating such light and driven by …

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 …

Vectorial nonlinear optics refers to the investigation of optical processes whose nonlinear
polarization (NP) undergoes spin-orbit-coupling (SOC) interactions where, in general, the …

X-ray beams carrying orbital angular momentum (OAM) are an emerging tool for probing
matter. Optical elements, such as spiral phase plates and zone plates, have been widely …

Spatial-polarization-independent (SPI) parametric conversion is the basis of many optical
applications, such as SPI frequency interfaces for communication channels carried by vector …

The rotational Doppler effect—the angular version of the Doppler effect—shows a frequency
shift phenomenon happening when light passes through a rotating object and its angular …

Nonlinear optical processes of spatially structured light such as optical vortices and vector
optical fields have exhibited many interesting physical effects and found a variety of …

Ideal full Poincaré (FP) beams contain all possible polarization states on the surface of the
Poincaré sphere and are readily created by linear optical techniques and, more recently, by …

The change in the relative phase between two light fields serves as a basic principle for the
measurement of the physical quantity that guides this change. It would therefore be highly …
