Liquid crystal displays (LCDs) and photonic devices play a pivotal role to augmented reality
(AR) and virtual reality (VR). The recently emerging high-dynamic-range (HDR) mini-LED …

Planar and ultrathin liquid crystal (LC) polarization optical elements have found promising
applications in augmented reality (AR), virtual reality (VR), and photonic devices. In this …

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 …

In this review paper, we report recent progress on Pancharatnam-Berry (PB) phase optical
elements, such as lens, grating, and deflector. PB lenses exhibit a fast switching time …

Liquid-crystal-based Pancharatnam–Berry phase optical elements (PBOEs), also known as
diffractive wave plates (DWPs), geometric phase optics (GPO), or geometric phase …

Wavefront control lies in the heart of optics. Multi‐degree orthogonal manipulation of light,
especially the on‐demand tailoring of the working band and spatial phase front, is expected …

Single-shot phase-shifting incoherent digital holography with multiplexed checkerboard
phase gratings is proposed for acquiring holograms of moving objects. The gratings …

Liquid-crystal (LC)-based ultrathin flat optical elements (FOEs) exhibit several attractive
properties, such as a high degree of optical tunability, strong polarization selectivity, nearly …

We demonstrate a high-efficiency achromatic, wide-view Pancharatnam–Berry phase
deflector (PBD) based on a three-layer multi-twist structure. A practical method to measure …

The ultimate augmented reality (AR) should be a glass-type see-through display with
uncompromised optical performances. The major technical challenge of present AR display …
