Monolithic Multiparameter Terahertz Nano/Microdetector Based on Plasmon Polariton Atomic Cavity (Adv. Mater. 11/2025)

Multiparameter Detection In article number 2410946, Ningsheng Xu, Shaozhi Deng, and co-workers propose plasmon polariton atomic cavity (PPAC) to construct monolithic multifunctional detector. With a footprint one-tenth the incident wavelength, the detector offers benchmarking intensity-, frequency-, and polarization-sensitive detection, rapid response, and sub-diffraction spatial resolution, all operating at room temperature across 0.22 to 4.24 THz. The unique advantages of PPAC detector make it promising for high-resolution imaging and polarization-coded communication.
