Journal ArticleDOI

Roadmap on plasmonics

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

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

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.
