Metasurfaces, planar metamaterials consisting of a single layer or several layers of artificial
structures, not only form the basis for fundamental physics research but also have …

We propose an efficient and robust method to generate tunable vector beams by employing
a single phase-type spatial light modulator (SLM). With this method, a linearly polarized …

Nowadays, the well-known cylindrical vector beams (CVBs)–the axially symmetric beam
solution to the full-vector electromagnetic wave equation–are widely used for advanced …

The origin of spin-orbit interaction of light at a conventional optical interface lies in the
transverse nature of the photon polarization: The polarizations associated with the plane …

The conversion between different polarizations generally requires an optical element or an
optical system. We demonstrate, theoretically and experimentally, that the conversion …

We propose a common criterion for the effect of Gouy phase on the distinct polarization
transition of focused vector vortex beams (VVBs). Such polarization transition is strongly …

Quantitative optical phase information provides an alternative method to observe biomedical
properties, where conventional phase imaging fails. Phase retrieval typically requires …

The spatial light modulator (SLM) is considered as an effective device to create beams with
inhomogeneous phases and polarizations, such as vortex beams and vector beams …

Based on the combined modulation of geometric phase introduced by a metasurface and
dynamic phase created by a plano-convex lens, we propose and demonstrate a simple and …
