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

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 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.

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 ...

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 ...

Dielectric metasurfaces represent one of the cutting-edge research and application directions in optics. They not only possess the advantage of low loss but also enable the realization of device ...

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

STMicroelectronics (ST), a developer of semiconductor technologies and Metalenz, which creates metasurface optics, have announced a new license agreement. The companies intend to broaden ST’s ...
