Super-resolution optical microscopy, which gives access to finer details of objects, is highly
desired for fields of nanomaterial, nanobiology, nanophotonics, etc. Many efforts, including …

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

We review recent progress in femtosecond laser anisotropic nanostructuring of transparent
materials, including silica glass and thin films. With different writing parameters, oblate …

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

Light with helical phase wavefront carries orbital angular momentum, a unique feature
widening the horizon of optical imaging applicability. Here, we take particular interest in the …

The possibility to achieve unprecedented multiplexing of light-matter interaction in
nanoscale is of virtue importance from both fundamental science and practical application …

Vector beams, beams with a non-uniform state of polarization, have become an
indispensable tool in many areas of science and technology. Harnessing topological light …

Nonscattering optical anapole condition is corresponding to the excitation of radiationless
field distributions in open resonators, which offers new degrees of freedom for tailoring light …

We report the generation of vector and vortex high-order harmonic beams in argon using the
femtosecond laser pulses propagated through the phase-modifying optical elements (S …

We introduce the universal upper bound of helicity density, which is the maximum helicity
light can have at a given light energy density. Helicity maximization as discussed here is …
