From 3D movie screens to augmented-reality devices, many modern technologies rely on our ability to manipulate light. Doing ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240076 , discusses spin-controlled generation of a complete polarization set with randomly-interleaved plasmonic metasurfaces.

Controlling both the state and degree of polarization of light is a long-standing challenge in optics. While metasurfaces offer compact, high-resolution control over wavefronts, most existing designs ...

A new LED design uses a built-in nanoscale metasurface to emit circularly polarized light directly, eliminating bulky optics ...

New research explores silicon nanorods in metasurfaces for polarization holographic encryption, addressing image recovery and ...

A project at Pennsylvania State University (Penn State) has developed a metasurface intended to extract polarimetric imaging data more rapidly and cost effectively than current methods. Described in ...

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

A new ultrathin photodetector captures light across the full spectrum in just 125 picoseconds, opening the door to faster, ...

Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to encode signals or images. Yet controlling these properties independently ...

Harvard University spin-out Metalenz says its metasurface optics - now being produced in volume by semiconductor foundry United Microelectronics Corporation (UMC) - are appearing in a new series of ...
