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

However, the high-refractive thin film that remains on the substrate after the pattern is formed scatters light, reducing the efficiency of the metasurface. The research team solved the limits of ...

Metasurface-based spatial light modulators can generate high-quality, dynamic holograms for augmented and virtual reality applications. Meta-optical devices can also be used to create thin, ...

Watch this thin, flexible material teach itself to mimic ocean waves and flexing palms in real-time. Relying on electromagnetic actuation, mechanical modeling and machine learning to form new ...

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 ...

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 ...

The key advance lies in controlling how light bends, or diffracts, when it hits the metasurface. Previous designs forced different orders of diffracted light to follow fixed patterns, like light ...
