Plasmonic Waveguides: Enhancing Quantum Electrodynamic Phenomena at Nanoscale

The emerging field of plasmonics may lead to enhanced light–matter interactions at extremely nanoscale regions. Plasmonic (metallic) devices promise efficiently control classical and quantum properties light. waveguides are usually employed excite confined electromagnetic modes that can strongly interact with matter. Analysis shows nanowaveguides share similarities their low-frequency microwave counterparts. In this article, we review ways study plasmonic nanostructures coupled optical emitters from a perspective. Quantum mainly used generate single-photon light be as bit, or “qubit,” in envisioned information technologies. We demonstrate different enhance diverse range electrodynamic phenomena based on configurations by using the Green’s function formalism, dyadic tensor. More specifically, spontaneous emission superradiance analyzed through function-based quantization. exciting new could plethora novel for communications computing applications realm, such efficient sources, sensors, compact on-chip nanophotonic circuits.
