For the academic journal, see Plasmonics (journal).
Plasmonics or nanoplasmonics[1] refers to the generation, detection, and manipulation of signals at optical frequencies along metal-dielectric interfaces in the nanometer scale.[2] Inspired by photonics, plasmonics follows the trend of miniaturizing optical devices (see also nanophotonics), and finds applications in sensing, microscopy, optical communications, and bio-photonics.[3][4]
