Abstract

We study the interaction between a planar Fabry–Perot microcavity and a single embedded gold nanoparticle. We record spatially resolved white-light transmission spectra and show that the interaction between microcavity and nanoparticle gives rise to a redshift of the cavity modes, in accordance with the Bethe–Schwinger cavity perturbation formula. The spectral tuning of cavity modes by discrete nanoparticles can be exploited for applications such as optical and micromechanical sensing.
