Nanogap-Enhanced Infrared Spectroscopy with Template-Stripped Wafer-Scale Arrays of Buried Plasmonic Cavities

Xiaoshu Chen, Cristian Ciracì, David R. Smith +1

We have combined atomic layer lithography and template stripping to produce a new class of substrates for surface-enhanced infrared absorption (SEIRA) spectroscopy. Our structure c…

Influence of the electron spill-out and nonlocality on gap-plasmons in the limit of vanishing gaps

M. Khalid, O. Morandi, E. Mallet +4

We study the effect of electron spill-out and of nonlocality on the propagation of light inside a gap between two semi-infinite metallic regions. We compare the predictions of a lo…

Free electron nonlinearities in heavily doped semiconductors plasmonics

Federico De Luca, Michele Ortolani, Cristian Ciracì

Heavily doped semiconductors have emerged as tunable low-loss plasmonic materials at mid-infrared frequencies. In this article we investigate nonlinear optical phenomena associated…

Mode-matching enhancement of second-harmonic generation with plasmonic nanopatch antennas

Ahsan Noor, Anoop R. Damodaran, In-Ho Lee +3

Plasmonic enhancement of nonlinear optical processes confront severe limitations arising from the strong dispersion of metal susceptibilities and small interaction volumes that ham…

Impact of surface roughness in nanogap plasmonic systems

Cristian Ciracì, Ferran Vidal-Codina, Daehan Yoo +3

Recent results have shown unprecedented control over separation distances between two metallic elements hundreds of nanometers in size, underlying the effects of free-electron nonl…

Influence of spatial dispersion on surface plasmons, nanoparticles and grating couplers

Armel Pitelet, Emmanuel Centeno, Antoine Moreau +5

Recent experiments have shown that spatial dispersion may have a conspicuous impact on the response of plasmonic structures. This suggests that in some cases the Drude model should…
