Abstract Recently discovered reflective Pancharatnam–Berry phase (PB phase) from chiral
anisotropic media (eg, cholesteric liquid crystal, CLC) has aroused great interest in the …

Replacing curved and bulky optical elements with thin and lightweight counterparts is a
persistent pursuit of the optical society. Metasurfaces, as two-dimensional artificial …

Liquid crystals (LCs) are key functional materials that are broadly adopted in various fields
due to their stimuli‐responsiveness. Recently, LCs with hierarchical architectures have …

Conventional lens technologies face great challenges in applications requiring large
apertures and small f‐numbers, while a liquid crystal (LC) lens based on geometric phase is …

Optical phased array (OPA), as a promising beam steering technology, however, usually
suffers from a narrow field of view (FOV) that limits its performances in applications. A …

Tunable liquid prism is important member of liquid optical devices, and its advantage over
solid material prism lies in the non-mechanical tunability. Therefore, it is of great value for …

Abstract Non-line-of-sight (NLOS) imaging aims at recovering hidden objects located
beyond the traditional line of sight, with potential applications in areas such as security …

We report two high birefringence and low viscosity nematic mixtures for phase-only liquid-
crystal-on-silicon spatial light modulators. The measured response time (on+ off) of a test …

A flat telescope (FTS), which incorporates an all-dielectric metasurface doublet (MD) based
on hydrogenated amorphous silicon nanoposts, is proposed and demonstrated to achieve …

Fourier ptychography (FP) imaging, drawing on the idea of synthetic aperture, has been
demonstrated as a potential approach for remote sub-diffraction-limited imaging …
