Augmented reality (AR) display, which superimposes virtual images on ambient scene, can
visually blend the physical world and the digital world and thus opens a new vista for human …

Artificial chiral nanostructures have been subjected to extensive research for their unique
chiroptical activities. Planarized chiral films of ultrathin thicknesses are in particular demand …

Optical metasurfaces with high quality factors (Q-factors) of chiral resonances can boost
substantially light-matter interaction for various applications of chiral response in ultrathin …

Vectorial holography has gained a lot of attention due to the promise of versatile polarization
control of structured light for enhanced optical security and multi-channel optical …

Metasurface-driven optical encryption devices have attracted much attention. Here, we
propose a dual-band vectorial metahologram in the visible and ultraviolet (UV) regimes for …

The combination of conventional polarization optical elements, such as linear polarizers and
waveplates, is widely adopted to tailor light's state of polarization (SOP). Meanwhile, less …

If a metalens integrates the circular polarization (CP) conversion function, the focusing lens
together with circular-polarizing lens (CPL) in traditional cameras may be replaced by a …

Metasurfaces, artificial 2D structures, have been widely used for the design of various
functionalities in optics. Jones matrix, a 2× 2 matrix with eight parameters, provides the most …

Innovative multiplexing technologies based on nano‐optics for anti‐counterfeiting have
been proposed as overt and covert technologies to secure products and make them difficult …
