“…Their optical properties, based on plasmonic resonances, can be predicted using design guidelines which have been developed starting from well-established techniques already in use at microwave frequencies [6,7]. Even though plasmonic antennas have been employed for many applications, metals suffer from large resistive heating losses in the visible and near-infrared (near-IR) wavelength range, which limit device performance [8,9]. Therefore, several recent works [8][9][10][11][12][13] have focused on a new class of all-dielectric optical nanoantennas.…”

“…Semiconductor nanoparticles are emerging as a promising alternative to metallic ones for a wide range of nanophotonic applications based on localized resonant modes in the entire visible and near-IR spectral ranges, see e.g [8][9][10]. Different particle geometries can be considered, but mainly spherical and cylindrical antennas have been dealt with to date.…”

Enhanced second-harmonic generation from magnetic resonance in AlGaAs nanoantennas

Abstract:We designed AlGaAs-on-aluminium-oxide all-dielectric nanoantennas with magnetic dipole resonance at near-infrared wavelengths. These devices, shaped as cylinders of 400nm height and different radii, offer a few crucial advantages with respect to the silicon-on-insulator platform for operation around 1.55μm wavelength: absence of two-photon absorption, high χ (2) nonlinearity, and the perspective of a monolithic integration with a laser. We analyzed volume χ (2) nonlinear effects associated to a magnetic dipole resonance in these nanoantennas, and we predict second-harmonic generation exceeding 10 −3 efficiency with 1GW/cm 2 of pump intensity.

Laser printing of silicon nanoparticles with resonant optical electric and magnetic responses

et al. 2014

View full text Add to dashboard Cite

Silicon nanoparticles with sizes of a few hundred nanometres exhibit unique optical properties due to their strong electric and magnetic dipole responses in the visible range. Here we demonstrate a novel laser printing technique for the controlled fabrication and precise deposition of silicon nanoparticles. Using femtosecond laser pulses it is possible to vary the size of Si nanoparticles and their crystallographic phase. Si nanoparticles produced by femtosecond laser printing are initially in an amorphous phase (a-Si). They can be converted into the crystalline phase (c-Si) by irradiating them with a second femtosecond laser pulse. The resonance-scattering spectrum of c-Si nanoparticles, compared with that of a-Si nanoparticles, is blue shifted and its peak intensity is about three times higher. Resonant optical responses of dielectric nanoparticles are characterized by accumulation of electromagnetic energy in the excited modes, which can be used for the realization of nanoantennas, nanolasers and metamaterials.

“…Although the electromagnetic properties of dielectric resonators have been studied for decades [47][48][49] , alldielectric infrared metamaterials have only recently been demonstrated 7,[50][51][52][53] , and other non-metallic materials are being considered 54 . Despite this body of work, experimentally demonstrating sharp metamaterial resonances (QB100) has proven to be challenging, thus greatly impeding further progress in applying metamaterials to practical problems such as biochemical sensing.…”

Spectrally selective chiral silicon metasurfaces based on infrared Fano resonances

Metamaterials and metasurfaces represent a remarkably versatile platform for light manipulation, biological and chemical sensing, and nonlinear optics. Many of these applications rely on the resonant nature of metamaterials, which is the basis for extreme spectrally selective concentration of optical energy in the near field. In addition, metamaterial-based optical devices lend themselves to considerable miniaturization because of their subwavelength features. This additional advantage sets metamaterials apart from their predecessors, photonic crystals, which achieve spectral selectivity through their longrange periodicity. Unfortunately, spectral selectivity of the overwhelming majority of metamaterials that are made of metals is severely limited by high plasmonic losses. Here we propose and demonstrate Fano-resonant all-dielectric metasurfaces supporting optical resonances with quality factors Q4100 that are based on CMOS-compatible materials: silicon and its oxide. We also demonstrate that these infrared metasurfaces exhibit extreme planar chirality, opening exciting possibilities for efficient ultrathin circular polarizers and narrow-band thermal emitters of circularly polarized radiation.
