A metasurface-enhanced thermal photodetector achieves 125 picosecond response times, approaching semiconductor speeds without external power or cooling while retaining broad wavelength flexibility.

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.
