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

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.

Polarization, which is one of the fundamental characteristics of electromagnetic wave, characterizes the vector nature of the oscillating electric field. Light beam with spatially homogeneous or ...

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 ...

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 ...

Researchers have developed a compact, single-shot polarization imaging system that can provide a complete picture of polarization. By using just two thin metasurfaces, the imaging system could unlock ...

Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to ...

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 ...

A tiny metasurface chip can turn invisible infrared light into steerable visible beams, opening the door to powerful new optical technologies.
