The main goal of the recent study by Cui and his colleagues was to devise an optimal scheme to efficiently retrieve and map ...

Scientists develop a metasurface that encrypts data using wavelength, wavevector direction, polarization, and diffraction order, enabling secure optical storage and holographic displays.

Using a liquid-crystal (LC)-based platform, the team designed an optical processor capable of handling hundreds of optical modes in a compact, two-dimensional setup. This breakthrough offers a ...

Imagine if self-driving cars couldn’t “see” people or objects around them, or if doctors lost an important tool for spotting early signs of cancer. These and many other systems rely on controlling ...

Achromatic metasurface waveguide technology is revolutionizing augmented reality (AR) displays by addressing the longstanding issue of chromatic aberration. Developed by a research team from China, ...

This innovative approach allows for the generation of multiphoton entanglement on a single metasurface, simplifying the process while making it more efficient. The researchers' method involves ...

Researchers have created a bilayer metasurface made of two stacked layers of titanium dioxide nanostructures, opening new possibilities for structuring light. Almost a decade ago, Harvard ...
