Subwavelength hybrid plasmonic structures for nonlinear nanophotonics [PDF]

open access: goldLight: Science & Applications, 2021
Plasmonic structures made of a semiconductor-insulator-metal hybrid provide efficient routes for second-harmonic and sum-frequency generation in sub-micrometer structures, which ultimately may boost on-chip integrated plasmonic circuits.

Designing anisotropy with waveguide subwavelength structures [PDF]

open access: yes2018 20th International Conference on Transparent Optical Networks (ICTON), 2018
Silicon sub-wavelength structures have become a versatile design tool for practical, high-performance integrated optical devices, ranging from highly efficient grating couplers to ultra-broadband beam-splitters.

Surface wave generation and propagation on metallic subwavelength structures measured by far-field interferometry [PDF]

open access: yes, 2006
Transmission spectra of metallic films or membranes perforated by arrays of subwavelength slits or holes have been widely interpreted as resonance absorption by surface plasmon polaritons (SPPs). Alternative interpretations involving evanescent waves diffracted on the surface have also been proposed.

Polarization quadrature measurement of subwavelength diffracting structures [PDF]

open access: yesApplied Optics, 1997
The amplitude and the phase of the diffracted far field depends on polarization when the diffracting structure is comparable to or less than the wavelength.

Soliton frequency shifts in subwavelength structures [PDF]

open access: hybridJournal of Optics, 2015
We investigate the soliton frequency shifts for few-cycle ultrashort laser pulses propagating through resonant media embedded within subwavelength structures, and we elucidate the underlying physics. Full-wave Maxwell?Bloch equations are solved numerically by using the finite-difference time-domain method.

Optical diffraction of focused spots and subwavelength structures [PDF]

open access: yesJournal of the Optical Society of America A, 1997
We have developed a numerical diffraction tool for cases in which the incident field is a focused spot and the diffracting structure is a single structure or an aperiodic surface.

Spectral scattering characteristics of subwavelength-sized spherical particles near Mie resonance modes probed by tightly focused Terahertz waves [PDF]

open access: yesScientific Reports
The complex dynamics of terahertz (THz) wave scattering by subwavelength-scale structures remain largely unexplored. This article examines the spectral scattering characteristics of subwavelength-sized spherical particles probed by tightly focused THz ...

Extra energy coupling through subwavelength hole arrays via stochastic resonance [PDF]

open access: yesarXiv, 2007
Interaction between metal surface waves and periodic geometry of subwavelength structures is at the core of the recent but crucial renewal of interest in plasmonics. One of the most intriguing points is the observation of abnormal strong transmission through these periodic structures, which can exceed by orders of magnitude the classical transmission ...
