While conventional photodetectors can only measure light intensity, the light field contains much richer information. This information includes but is not limited to phase, polarization, and spectrum.

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 ...

The terahertz (THz) band of the electromagnetic spectrum holds immense promise for next-generation technologies, including high-speed wireless communication, advanced encryption, and medical imaging.

A new dual-broadband liquid-crystal programmable metasurface (LCPM) has been proposed to support terahertz wireless communications in ...

Researchers have developed a compact quantum detector that makes terahertz radiation much easier to detect. A specially designed metasurface funnels incoming energy into tiny active regions, greatly ...

(a) Schematic of non-local mode selection by metasurface-integrated quantum analog operation. F^1, F^2, F^3, and F^4 are the differential operators. The green area has been designed to construct ...

Terahertz wireless communication is a promising technology for future networks, but it often fails when line-of-sight paths are blocked. A new study ...
