The geometric Pancharatnam-Berry (PB) phase not only is of physical interest but also has
wide applications ranging from condensed-matter physics to photonics. Space-varying PB …

Over the past 30 years, physical optics has been enriched by the appearance of singular
optics as a new branch approved in scientific classifiers. This review briefly outlines the main …

A novel terahertz (THz) sensing scheme is proposed based on the photonic spin Hall effect
(PSHE). By illumining a paraxial Gaussian THz beam onto a black phosphorus (BP)-based …

Diffraction of light of a visible spectral range by subwavelength metal gratings has been
investigated experimentally and theoretically using rigorous electromagnetic calculations. It …

Singular optics and metamaterials are both fascinating branches of modern optics. While the
twist of vortex beams in phase and polarization leads to singularities, the twist of …

Recently, optical vortices (OVs) have attracted substantial attention because they can
provide an additional degree of freedom, ie, orbital angular momentum (OAM). It is well …

Herein, the generation of an optical vortex array dubbed the flower‐shaped optical vortex
array (FOVA) is proposed and experimentally demonstrated using a single optical path …

In this paper, we propose a weak measurement method using two pointers to estimate the
magneto-optical Kerr angle, which is robust to ellipticity. The double pointers are the …

Weak measurement as a nonperturbative theory has been shown to be powerful in the
fundamentals of quantum mechanics and high-precision metrology, in which the pointer is of …

Generating the high-power optical vortex (OV) gains growing attention in a variety of
applications such as materials processing, laser ablation, long-distance optical …
