Optical trap** describes the interaction between light and matter to manipulate micro-
objects through momentum transfer. In the case of 3D trap** with a single beam, this is …

Orbital angular momentum (OAM) of light is an important feature of structured
electromagnetic fields exhibiting non-uniform spatial distribution. In contrast to a spin …

In this work we experimentally demonstrated an underwater wireless optical
communications (UWOC) link over a 2.96 m distance with two 445-nm fiber-pigtailed laser …

We propose a method to determine the topological charge (TC) of a perfect vortex. With the
phase shift technique, the perfect vortex and its conjugate beam exactly overlap and …

Low-refractive-index microparticles, such as hollow microspheres, have shown great
significance in some applications, such as biomedical sensing and targeted drug delivery …

Laguerre–Gaussian beams of integer azimuthal index satisfy the fundamental principle of
quantization of orbital angular momentum. Here, we consider light-induced orbiting of a …

The perfect optical vortex (POV), the ring size being independent of its topological charge,
has found potential applications in optical tweezers and optical communications. In this …

Photopolymerization is a powerful technique to create arbitrary micro-objects with a high
spatial resolution. Importantly, to date all photopolymerization studies have been performed …

Over the past 36 years much research has been carried out on Bessel beams (BBs) owing to
their peculiar properties, viz non-diffraction behavior, self-healing nature, possession of well …

Perfect (optical) vortices (PVs) have the mooted ability to encode orbital angular momentum
(OAM) onto the field within a well-defined annular ring. Although this makes the near-field …
