Abstract
We proposed to explore room-temperature quantum devices operating at the single-photon level, with functionalities that can be tailored changing different parameters of a plasmonic metamaterial composed of hollow truncated nanocones that greatly enhance the photonic density of states. We study numerically and experimentally the photonic properties of this material supporting very high field enhancement with dipolar and quadrupolar plasmonic modes as functions of angle and polarization of illumination. We measure the dependence of their resonance wavelengths on different device parameters and surrounding media of this new nanomaterial platform. Depending on the desired resonant wavelengths, this new material platform can be designed for applications in SERS, nonlinear, sensing, and single-photon emission control.
