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

To realize integrated and compact designs, metasurface elements have been used in polarization and multispectral optical systems. However, there remains a lack of metalens devices that can achieve ...

The SEAS-led metasurface revolution of the last decade has produced flat, ultra-thin structures patterned with millions of tiny elements that can manipulate light with nanometer precision. A striking ...

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 sending ...
