Corner Reflector Plasmonic Nanoantennas for Enhanced Single-Photon Emission [PDF]

open access: goldApplied Sciences
The emission rate of atom-like photon sources can be significantly improved by coupling them to plasmonic resonant nanostructures. These arrangements function as nanoantennas, serving the dual purpose of enhancing light–matter interactions and decoupling
