Abstract
Application of quantum entangled photons is now extending to various fields in physics, chemistry and biology. In particular, in terms of application to molecular science, broadband ultraviolet frequency-entangled photons are desired because molecules inducing photochemical reactions of interest often have electronic transition energies in the ultraviolet region. Recent standard method for generating such entangled photons is a chirped quasi-phase-matching method, however this method is not suitable for the generation of ultraviolet frequency-entangled photons because it requires down-conversion of a photon with a wavelength shorter than ultraviolet into an entangled photon pair. Here we propose a simple method for generating broadband ultraviolet frequency-entangled photons using cavity quantum plasmonics, in which conventional cavity quantum electrodynamics theory is applied to quantum plasmonics. We introduce a cavity-plasmon system in which localised surface plasmon (LSP) is coupled to the cavity fields of a state-of-the-art microcavity. Using this system, we theoretically show that broadband ultraviolet frequency-entangled photons can be generated simply by utilising the absorption saturation effect of LSP.
Highlights
OPEN Generation of broadband ultraviolet frequency-entangled photons using cavity quantum
Either one of two input photons is absorbed by the localised surface plasmon (LSP) and the other remains unabsorbed owing to the absorption saturation effect of LSP
By introducing a simple quantisation method of LSP and a one-dimensional cavity-plasmon system, we have proposed a simple method for generating broadband ultraviolet frequency-entangled photons by utilising cavity quantum plasmonics
