Optical metasurfaces, with their ultra-thin and lightweight properties, are driving the miniaturization and planarization of optical systems. However, their development from unit-cell design to system ...

Artificial intelligence speeds metasurface design from unit cells to full optical systems, enabling compact imaging, AR and VR displays and advanced LiDAR. (Nanowerk News) Optical metasurfaces, with ...

A new material platform has enabled scientists to create photon pairs whose entanglement can be tuned from a layer thinner than a human hair. The photon pairs are created by a metasurface made of ...

The research team proposed a method called aberration-converged annular lithography (ACAL) system, as schematic diagram shown in Figure 1. The Gaussian beam is converted into a collimated annular beam ...

Researchers use large language models to streamline nanoscopic material design for advanced optical systems like camera lenses and VR headsets. (Nanowerk News) A team of researchers at Penn State have ...

Being able to see light and detect radiation is of utmost importance at any frequency. While this challenge has been solved in the visible range, radiation detectors in the far-infrared and terahertz ...
