Abstract

The authors have presented experimental evidence for Fano-type resonances in single plasmonic nanoresonators. As both the spectral position and the width of these Fano line shapes depend very sensitively on the dielectric gap between the individual resonators sustaining the dark and bright modes, respectively, a high sensitivity for the sensing of molecular species within the gap region can be anticipated. This constitutes a promising application potential of such resonator structures.
