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 …

Although the photonic spin‐Hall effect (PSHE) at optical interfaces has been widely studied
in past years, its physical origin remains obscure. Here, through studying the scatterings of …

Spin‐controlled vortex generation and spin‐Hall effect, two distinct effects discovered in
optics, have been extensively studied recently. However, while physical origins of two effects …

Several works on optical higher-order differential operations have recently attracted
attention, particularly in image processing for edge detection. However, the inefficient …

We experimentally demonstrate a two-dimensional topological differential microscopy based
on the spin–orbit interaction of light through a thin uniaxial crystal slab. First, a three …

The topology-induced phase transition (TPT) in spin-orbit optics refers to a process of
topological transition from one kind of spin-orbit interaction (eg, spin-controlled vortex …

We employ a full-wave theory to systematically investigate two types of spin-orbit
interactions and their topological phase transitions for various light beams (eg, Laguerre …

The photonic spin Hall effect (PSHE), featured by a spin-dependent shift driven by its
polarization handedness, is proposed to facilitate the applications in precision metrology …

ABSTRACT A light beam reflected and refracted at a sharp interface can acquire a
momentum-dependent Pancharatnam–Berry (PB) phase, which produces a topological …

Temporal metamaterials, based on time-varying constitutive properties, offer new exciting
possibilities for advanced field manipulations. In this study, we explore the capabilities of …
