Bound states in the continuum (BICs) have attracted attention in photonics owing to their
interesting properties. For example, BICs can effectively confine light in a counterintuitive …

Many polarisation techniques have been harnessed for decades in biological and clinical
research, each based upon measurement of the vectorial properties of light or the vectorial …

<? pag\vskip-16pt?> Harnessing linear and angular momenta of light is one of the
cornerstones in modern optics and has found tremendous applications in optical circuits …

The photonic spin Hall effect (SHE) refers to the transverse spin separation of photons with
opposite spin angular momentum, after the beam passes through an optical interface or …

This article reviews recent progress leading to the generation of optical vortex beams. After
introducing the basics of optical vortex beams and their promising applications, we …

Two-dimensional transition metal dichalcogenides (TMDCs) present extraordinary
nonlinearities and direct bandgaps at the K and K′ valleys. These valleys can be optically …

As the two most representative operation modes in an optical imaging system, bright-field
imaging and phase contrast imaging can extract different morphological information on an …

Planar optical elements that can manipulate the multidimensional physical parameters of
light efficiently and compactly are highly sought after in modern optics and nanophotonics. In …

The photonic spin Hall effect (PSHE) plays an important role in both fundamental science
and precision metrology. In this paper, we theoretically propose a polarization-dependent …

Optical bound states in the continuum (BICs) are exotic topological defects in photonic
crystal slabs, carrying polarization topological vortices in momentum space. The topological …
