With rapid advances in high-speed communication and computation, augmented reality
(AR) and virtual reality (VR) are emerging as next-generation display platforms for deeper …

Augmented reality (AR) displays, as the next generation platform for spatial computing and
digital twins, enable users to view digital images superimposed on real-world environment …

Holographic optical elements (HOEs) exhibit several unique properties in arbitrary wavefront
recording and extraction. Versatile recording mechanisms and material availabilities further …

Metasurface-based structural coloration is a promising enabling technology for advanced
optical encryption with a high-security level. Herein, we propose a paradigm of electrically …

Liquid crystals (LCs) possess some typical liquid properties, such as fluidity, the inability to
support shear, and the formation and coalescence of droplets, which exhibit optical …

Continuous, wide field-of-view, high-efficiency, and fast-response beam steering devices are
desirable in a plethora of applications. Liquid crystals (LCs)—soft, bi-refringent, and self …

Augmented reality (AR) displays are attracting significant attention and efforts. In this paper,
we review the adopted device configurations of see-through displays, summarize the current …

Conventional polymer dispersed liquid crystal (PDLC) films have been successful as
electrically‐switchable screens for privacy applications. However, spatial patterning of the …

We demonstrate a reflective liquid-crystal polarization volume grating with high efficiency for
augmented reality displays. The coupling efficiency was measured to be 90% at 650 nm and …

Optical data storage has had a major impact on daily life since its introduction to the market
in 1982. Compact discs (CDs), digital versatile discs (DVDs), and Blu‐ray discs (BDs) are …
