Throughout the evolution of AR technology, display systems have consistently aimed for a balance between clarity and compactness. Diffractive waveguides, known for their slim profiles, have become ...

A chip smaller than one square millimeter stores 160 holographic images at arbitrary 3D coordinates, with each spatial ...

Researchers have designed and demonstrated a new optical component that could significantly enhance the brightness and image quality of augmented reality (AR) glasses. The advance brings AR glasses a ...

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics. These engineered materials offer precise control over lights behavior, but ...

These devices are the first to demonstrate simultaneous control of all four optical degrees of freedom, namely, amplitude, phase, polarization ellipticity, and polarization orientation--a world record ...

Fig. 1 The design and characteristics of dielectric metasurface supporting Q-BIC mode. (a) The schematic of metasurface unit. (b) Distribution of electric and magnetic fields within x and y ...
