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 …

Polarization, the path traced by light's electric field vector, appears in all areas of optics. In
recent decades, various technologies have enabled the precise control of light's polarization …

Diffractive liquid-crystal optics is a promising optical element for virtual reality (VR) and
mixed reality as it provides an ultrathin formfactor and lightweight for human factors and …

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

Conventional stereoscopic three-dimensional displays suffer from vergence-accommodation
conflict because the stimulus to accommodation is fixed by the display panel and viewing …

The geometric Pancharatnam-Berry (PB) phase not only is of physical interest but also has
wide applications ranging from condensed-matter physics to photonics. Space-varying PB …

We present Holographic Glasses, a holographic near-eye display system with an
eyeglasses-like form factor for virtual reality. Holographic Glasses are composed of a pupil …

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 …

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