Researchers have overcome the limitations of existing metasurface technologies and successfully designed a Janus metasurface capable of perfectly controlling asymmetric light transmission. Metasurface ...

A PT-symmetric non-Hermitian photonic system composed of specifically designed metal structures is used to conduct arbitrary polarization transition from the equator and generate polarization vortices ...

Sketch of polarization entanglement from an InGaP metasurface. The nanostructured InGaP metasurface enables enhanced generation of polarization-entangled photon pairs counterpropagating along the z ...

A new material platform has enabled scientists to create photon pairs whose entanglement can be tuned from a layer thinner than a human hair. Subscribe to our newsletter for the latest sci-tech news ...

(Nanowerk News) Metasurface technology is an advanced optical technology that is thinner, lighter, and capable of precisely controlling light through nanometer-sized artificial structures compared to ...
