Quantum plasmonic nanoantennas
We study plasmonic excitations in the limit of few electrons, in one-atom thick sodium chains, and characterize them based on collectivity. We also compare the excitations to classical localised plasmon modes and find for the longitudinal mode a quantum-classical transition around 10 atoms. The transverse mode appears at much higher energies than predicted classically for all chain lengths. The...
متن کاملPlasmonic nickel nanoantennas.
The fundamental optical properties of pure nickel nanostructures are studied by far-field extinction spectroscopy and optical near-field microscopy, providing direct experimental evidence of the existence of particle plasmon resonances predicted by theory. Experimental and calculated near-field maps allow for unambiguous identification of dipolar plasmon modes. By comparing calculated near-fiel...

متن کاملMultiple-wavelength plasmonic nanoantennas.
We propose a type of photonic-plasmonic antennas capable of focusing light into subwavelength focal point(s) at several wavelengths, which are formed by embedding conventional dimer gap or bow-tie nanoantennas into multiple-periodic gratings. Fano-type coupling between localized surface plasmon resonances of dimer antennas and photonic modes in the gratings adds new functionalities, including m...
متن کاملPlasmonic nanoantennas for efficient control of polarization-entangled photon pairs
We suggest a source of polarization-entangled photon pairs based on a cross-shaped plasmonic nanoantenna driven by a single quantumdot. The integration of the nanoantennawith ametalmirror overcomes the fundamental tradeoff between the spontaneous emission (SE) enhancement and the extraction efficiency typical ofmicrocavityand nanowire-based architectures.With a very high extraction efficiency o...
