Geometric phase is a unifying and central concept in physics, including optics. As a matter of
fact, optics played a pivotal role from the inception of this new paradigm, as some of the first …

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 …

Spatiotemporal sculpturing of light pulse with ultimately sophisticated structures represents a
major goal of the everlasting pursue of ultra-fast information transmission and processing as …

Polarization and geometric phase sha** via a space-variant anisotropy has attracted
considerable interest for fabrication of flat optical elements and generation of vector beams …

Optical interactions are governed by both spin and angular momentum conservation laws,
which serve as a tool for controlling light–matter interactions or elucidating electron …

INTRODUCTION Light beams carry both energy and momentum, which can exert a small
but detectable pressure on objects they illuminate. In 1992, it was realized that light can also …

Structured light, which exhibits nontrivial intensity, phase, and polarization patterns in space,
has key applications ranging from imaging and 3D micromanipulation to classical and …

Since the second half of the 20th century, ideas to develop methods for the formation of
optical vortices (OVs) or OV beams–regions of circular motion of energy flow in an …

Structured light in the short-wavelength regime opens exciting avenues for the study of
ultrafast spin and electronic dynamics. Here, we demonstrate theoretically and …

The landscape of ultrafast structured light pulses has significantly advanced thanks to the
ability of high-order harmonic generation (HHG) to translate the spatial properties of infrared …
