With its unique and exclusive linear and nonlinear optical characteristics, epsilon-near-zero
(ENZ) photonics has drawn a tremendous amount of attention in the recent decade in the …

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 …

Optical beam shifts, which mainly refer to the Goos–Hänchen shift and spin-Hall shift, widely
exist in basic optical processes such as interface reflection and refraction. They are very …

The terahertz band has been historically hindered by the lack of efficient generators and
detectors, but a series of recent breakthroughs have helped to effectively close the “terahertz …

It has been known that an optical vortex with a topological charge±2 can be generated as a
circularly polarized (CP) light beam propagates in a bulk uniaxial crystal, but its physical …

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 …

Topological photonics provides exciting and emerging opportunities for the manipulation of
light. As the photonic analogue of quantum Hall edge states, chiral edge modes, arising at …

The interaction of light beams with resonant structures has led to the development of various
optical platforms for sensing, particle manipulation, and strong light–matter interaction. In the …
