Harnessing the natural resonances of time-varying dispersive interfaces
Carlo Rizza, Maria Antonietta Vincenti, Giuseppe Castaldi +3
Space-time modulation of electromagnetic parameters offers novel exciting possibilities for advanced field manipulations. In this study, we explore wave scattering from a time-vary…
Dramatic enhancement of second and third harmonic generation in gold nanogratings in the visible and UV ranges
S. Mukhopadhyay, L. Rodriguez-Suné, C. Cojocaru +7
Notwithstanding its long history, the study of nonlinear optics from metal surfaces is still an active field of research. For instance, in view of the presence of absorption questi…
Retrieving linear and nonlinear optical dispersions of matter: combined experiment-numerical ellipsometry in Silicon, Gold and Indium Tin Oxide
L. Rodriguez-Sune, J. Trull, N. Akozbek +4
The predominant methods currently used to determine nonlinear optical constants like the nonlinear refractive index n2 or chi3 rely mostly on experimental, open and closed z-scan t…
Harmonic generation from gold nanolayers: an old problem under a new light
L. Rodríguez-Suné, J. Trull, C. Cojocaru +4
Understanding how light interacts at the nanoscale with metals, semiconductors, or ordinary dielectrics is pivotal if one is to properly engineer nano-antennas, filters and, more g…
ENZ materials and Anisotropy: Enhancing Nonlinear Optical Interactions at the Nanoscale in Metal/Conducting-Oxide Multilayer Stacks
Maria Antonietta Vincenti, Domenico de Ceglia, Michael Scalora
Epsilon-near-zero materials are exceptional candidates for studying electrodynamics and nonlinear optical processes at the nanoscale. We demonstrate that by alternating a metal and…
Electrodynamics of Conductive Oxides: Intensity-dependent anisotropy, reconstruction of the effective dielectric constant, and harmonic generation
Michael Scalora, Jose Trull, Domenico de Ceglia +5
We study electromagnetic pulse propagation in an indium tin oxide nanolayer in the linear and nonlinear regimes. We use the constitutive relations to reconstruct the effective diel…
