Orbital angular momentum (OAM) beams with topological charge ℓ are commonly generated
and detected by modulating an incoming field with an azimuthal phase profile of the form …

Metasurface provides miniaturized devices for integrated optics. Here, we design and
realize a meta-converter to transform a plane-wave beam into multiple Laguerre-Gaussian …

We report the diversiform propagation of hollow Gaussian beam clusters in non-linear media
with self-induced parabolic potentials. It is found that the beam cluster can present various …

We demonstrate here an experimental observation on generation and conditional switching
between π-symmetric isolated C-points such as lemon and star in a few mode optical fiber …

We have derived a set of equations for beam waist at lens focus as a function of variable
spot size and demonstrated their physical validity. The derived equations are useful for the …

Based on the vector angular spectrum representation, the contributions of the propagating
and evanescent waves to the vector vortex Laguerre–Gaussian beams on the higher-order …

The manipulations of nanoscale multi-channel vector beams (VBs) by metasurfaces hold
potential applications in various important fields. In this paper, the metasurface with two sets …

Conventional systems exploiting dynamic control of spatiotemporal beams using spatial light
modulators are limited in data rate and power density. These are not the only limits, since …

Achieving higher dimensionality in quantum protocols is receiving increasing interest at the
promise of a range of benefits, starting from increased information capacity to noise …

The arbitrary vector vortex beams on a higher-order Poincaré sphere (HOPS) are generated
and manipulated using the combination of a Mach–Zehnder interferometer and a spatial …
