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…
Laplacian-Level Quantum Hydrodynamic Theory for Plasmonics
Henrikh M. Baghramyan, Fabio Della Sala, Cristian Ciracì
An accurate description of the optical response of subwavelength metallic particles and nanogap structures is a key problem of plasmonics. Quantum hydrodynamic theory (QHT) has eme…
A nested hybridizable discontinuous Galerkin method for computing second-harmonic generation in three-dimensional metallic nanostructures
Ferran Vidal-Codina, Ngoc-Cuong Nguyen, Cristian Ciraci +2
In this paper, we develop a nested hybridizable discontinuous Galerkin (HDG) method to numerically solve the Maxwell's equations coupled with the hydrodynamic model for the conduct…
