Proposal for a Self-Excited Electrically Driven Surface Plasmon Polariton Generator
Abstract
We propose a generator of surface plasmon polaritons (SPPs) which, unlike spasers or plasmon lasers, does not require stimulated emission in the system. Its principle of operation is based on a positive feedback which a classical oscillating dipole experiences from a reflective surface located in its near field. The generator design includes a nanocavity between two metal surfaces which contains metal nanoparticles in its interior. The whole structure is placed onto a prism surface that allows one to detect the generated SPPs in the Kretschmann configuration. The generation process is driven by a moderate constant voltage applied between the metal covers of the cavity. Both the generation criterion and the steady-state operation of the generator are discussed.
