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…
Enhancing second-harmonic generation with electron spill-out at metallic surfaces
Muhammad Khalid, Cristian Ciracì
Second-order nonlinear optical processes do not manifest in the bulk of centrosymmetric materials, but may occur in the angstroms-thick layer at surfaces. At such length-scales, qu…
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…
