Fig. 1. (a) THz optical path diagram based on metasurface. By controlling the phase delays of LCP and RCP waves by unit cells, metasurface can transmit the LCP and RCP components of the incident ...

Light fields, as a form of electromagnetic waves, are characterized by fundamental parameters including intensity, phase, and polarization. Precise imaging of these three parameters is crucial for ...

A new single-layer chiral metasurface detects circularly polarized light efficiently, offering a compact, high-performance alternative to bulky optical systems. (Nanowerk News) Detecting circularly ...

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

(Nanowerk Spotlight) Light carries information in its wavelength, wavevector direction, polarization, and the way it bends through materials. Until now, optical data storage has typically used just ...

Quantum information processing is a field that relies on the entanglement of multiple photons to process vast amounts of information. However, creating multiphoton entanglement is a challenging task.

Holography—the science of recording and reconstructing light fields—has long been central to imaging, data storage, and encryption. Traditional holographic systems, however, rely on bulky optical ...
