TL;DR: In this paper, the authors present a broad overview of modern plasmonics, including quantum plasmons based on the quantum-mechanical properties of both the underlying materials and the plasons themselves (such as their quantum generator, spaser, etc.).
Journal ArticleDOI
Multipolar Interference for Directed Light Emission
TL;DR: This single-element antenna design robustly directs emission even when covered with nanometric emitters at random positions, outperforming previously demonstrated nanoantennas with a bandwidth of 200 nm and a directivity of 10.1 dB from a subwavelength structure.
Journal ArticleDOI
Resonant plasmonic nanoparticles for multicolor second harmonic imaging
Nicolò Accanto,Lukasz Piatkowski,Ion M. Hancu,Jan Renger,Niek F. van Hulst,Niek F. van Hulst +5 more
TL;DR: In this article, the use of resonant plasmonic nanoparticles, combined with broadband phase-controlled laser pulses, is presented as tunable sources of multicolor second harmonic generation.
Journal ArticleDOI
Selective excitation of individual nanoantennas by pure spectral phase control in the ultrafast coherent regime
Nicolò Accanto,Nicolò Accanto,Pablo M. de Roque,Marcial Galvan-Sosa,Ion M. Hancu,Niek F. van Hulst,Niek F. van Hulst +6 more
TL;DR: In this paper, the phase control of the two-photon induced photoluminescence (TPPL) in resonant gold nanoantennas is demonstrated by compressing pulses shorter than the localized surface plasmon dephasing time (<20 fs).
Proceedings ArticleDOI
Magneto-electric antennas for directed light emission
TL;DR: In this paper, a U-shaped split-ring resonator with a narrow gap was proposed to enhance the coupling of electric dipole sources to the antenna modes, which can enhance the radiated power enhancement and unidirectional emission.
