Abstract
Exact quantitative understanding of plasmon propagation along nanowires is mandatory for designing and creating functional devices. Here we investigate plasmon transmission through top-down-fabricated monocrystalline gold nanowires on a glass substrate. We show that the transmission through finite-length nanowires can be described by Fabry–Pérot oscillations that beat with free-space propagating light launched at the incoupling end. Using an extended Fabry–Pérot model, experimental and simulated length-dependent transmission signals agree quantitatively with a fully analytical model.
