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 …

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 …

Bifacial monolithic perovskite/silicon tandem solar cells exploit albedo—the diffuse reflected
light from the environment—to increase their performance above that of monofacial …

Chromatic aberration (CA) is a critical issue in immersive virtual reality displays. The current
digital compensation method can reduce the CA by pre‐processing the image contents but …

Vector optical field (VOF) manipulation greatly extended the boundaries of traditional scalar
optics over the past decades. Meanwhile, the newly emerging techniques enabled by …

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 …

Liquid crystal (LC) circular polarization gratings (PGs), also known as Pancharatnam–Berry
(PB) phase deflectors, are diffractive waveplates with linearly changed optical anisotropy …

We use a simple photoalignment method to fabricate four reflective cholesteric liquid crystal
(CLC) polymeric lenses with diameter D= 2.45 cm and low f-numbers (f/2, f/0.9, f/0.45, f/0.33) …

Diffractive optical elements (DOEs) are increasingly used as lightweight and compact
solutions in photonic devices. Steering of light and manipulation of the polarization can be …

Patterned liquid crystal (LC) configurations find widespread applications in functional
devices such as lenses, gratings, displays and soft-robots. In combination with external …
