Abstract

International audience; Controlling the optical coupling between the plasmonic resonances in a periodic array of metallic dimers represents unique opportunities for enhancing light-matter interactions, thereby driving many applications ranging from detectors, sensors, data storage, and improved light sources to photovoltaics [1,2]. Here, we study the surface lattice resonance modes supported by square arrays of three different gold dimer nanoantennas geometries (bowties, kissing cylinders, coupled ellipsoids), and their coupling to the gap plasmon modes of the individual dimers.

Abstract

Multi-resonant plasmonic simple geometries like nanocylinders and nanorods are highly interesting for two-photon photoluminescence and second harmonic generation applications, due to their easy fabrication and reproducibility in comparison with complex multi-resonant systems like dimers or nanoclusters. We demonstrate experimentally that by using a simple gold nanocylinder we can achieve a double resonantly enhanced two-photon photoluminescence of quantum dots, by matching the excitation wavelength of the quantum dots with a dipolar plasmon mode, while the emission is coupled with a radiative quadrupolar mode. We establish a method to separate experimentally the enhancement factor at the excitation and at the emission wavelengths for this double resonant system. The sensitivity of the spectral positions of the dipolar and quadrupolar plasmon resonances to the ellipticity of the nanocylinders and its impact on the two-photon photoluminescence enhancement are discussed.

Abstract

International audience; The active control of the quantum dots (QD) photoluminescence (PL) is a challenge for many applications, including the development of new commercial LEDs or new single photon sources in the emerging field of quantum nanooptics. A way to modulate the QD’s luminescence is to combine them with chromophores. Indeed, by a Förster resonance energy transfer (FRET) process, a donor fluorophore can transfer its energy to an acceptor chromophore, without the involvement of photons. Interesting dyes are those, which exhibit photochromism properties. Indeed, due to their ability to optically switch between two molecular states with different absorption properties, the photochromic molecules (PM) have been used to actively control the QD’s PL1. As this modulation is based on an energy transfer from the QD, the PL can never reach a higher intensity than the one emitted by the QD alone. However, it has been proven that the PL intensity can be enhanced by coupling the QDs to plasmonic nanoparticles (NPs), like metallic nanoparticles 2. In this talk, we report on the optical control of the de-excitation pathways of a coupled system between CdSe/ZnS QDs and silver nanocylinders of varying diameters using the conformational change of photochromic spiropyran molecules 3. We use Fluorescence Lifetime Imaging Microscopy (FLIM) to record quantum dots (QDs) photoluminescence lifetime and intensity before and after the photochromic transition.

Abstract

International audience; Metallic nanoparticles (MNP) may sustain Localized Surface Plasmon (LSP) resonances and the coupling between MNP and quantum dots (QD) is known to lead either to the enhancement or to the quenching of the QD photoluminescence [1]. The distance between QD and MNP is one of the switch parameters between both regimes. The goal of this study is to control the coupling distance (different from the physical distance) between QD and MNP by changing the refractive index of the surrounding medium using photochromic molecules (PM). These molecules are optical switches, which move from a transparent state to a colored one by absorbing UV light. The main drawback concerns the spectral overlap and the lifetime of each optical phenomenon, since the photochromic molecules can couple to LSP to induce strong coupling [2] or couple to QDs to quench the photoluminescence [3]. In this study, we measured photoluminescence spectra, images and lifetimes of QDs deposited on a glass substrate, with or without the presence of MNPs and PM.

Abstract

International audience; The optical characterization of a single metallic nanostructure has a strong interest in the scientific community owing to its localized surface plasmon resonances. For a single nano-object, the simplest and the accepted optical characterization technique is dark-field spectroscopy, even if there are many drawbacks and a certain complexity to operate it. We propose here using extinction spectroscopy of nanoparticles ensembles to characterize optically a single nanostructure. The scattering spectrum of a single gold nanocylinder and the extinction spectrum of a well-chosen array show similar results. We perform an experimental and numerical comparative study to draw parallels between both techniques.

Abstract

International audience; Second Harmonic Generation (SHG) is well known to be a powerful imaging tool for background‐free and nondamaging live tissues investigation. Incidentally, field enhancements in plasmonic nanostructures are often exploited to effectively compensate for the lack of phase‐matching in confined volumes. Proper optimization of such phenomena may allow realizing biosensing platforms based on nanoscale nonlinear sources. Recently, we reported single‐crystalline gold nanoantennas working in the near‐infrared that show unprecedented SHG efficiency thanks to (i) a multi‐resonant response occurring at both the excitation and SH wavelength, (ii) a significant spatial overlap of the localized fields at the wavelengths of interest and (iii) a broken‐symmetry geometry to achieve dipole‐allowed SHG. The effective combination of these key features in a single plasmonic antenna, characterized by the absence of local defects, allowed for the optimization of SHG efficiency in a well‐controlled fashion. Here, by expanding the paradigm for SHG enhancement to extended metasurfaces of nanoantennas, we aim at realizing a nonlinear platform that can be easily integrated in standard biosensing devices, since it can be excited by a weakly‐focused light. To this purpose, using electron beam lithography (EBL), we developed a first prototypical device based on a 10x10 um2 array of closely‐packed L‐shaped antennas. We have characterized the nonlinear response of this device using a homemade confocal microscope equipped with a 0.7 numerical aperture (NA) objective (Nikon) working in epireflection, coupled to a 120 fs laser centered at 1550 nm. By comparing experiments and simulations, we found that in this device SHG is dominated by the plasmonic resonance of the antennas at the fundamental wavelength. When comparing the average SHG from the array with the signal from individual L‐shape nanoantennas, an enhancement of about 15‐20 times is found that, considering about 50 antennas under the illumination spot, implies a drop in the emission efficiency of the individual antennas. Indeed, FDTD simulations demonstrate that, while a single antenna has a directional emission peaking away from the sample normal, the square‐lattice array radiates only through the (0,0) diffraction order (i.e. normal to the sample). The effective second harmonic emission from the array is then the convolution between the single‐antenna radiation pattern and the array diffraction pattern. This effectively inhibits some of the SH radiation that would be emitted by the isolated nonlinear antennas, which gets dissipated in the array itself. The relatively high NA employed, used here to probe possible inhomogeneities in sample fabrication, allows one to efficiently collect SHG from both the array and the individual antennas. On the contrary, calculations show that using a NA as small as 0.2 all of the SHG from the individual antennas would be lost while more than 80% of the SHG emitted by the array could still be collected. This is achieved thanks to the grating effect of the array, which strongly confines the light emission into a very small solid angle. If properly optimized, this emission mode‐matching paradigm could lead to the implementation of simple filterless and objective‐free nonlinear biosensors.

Abstract

International audience; Surface plasmon resonances can couple with molecular resonances (excitons) leading to weak or strong coupling regimes. The latter is always observed when the plasmon or the molecular exciton presents a large oscillator strength (high-Q plasmonic cavities or J-aggregates). We report here the observation of a strong coupling regime between the surface plasmon resonance of a nanoparticle array and the molecular excited state of photochromic molecules, both of them presenting weak oscillator strength.

Abstract

International audience; A localized surface plasmon resonance (LSPR) generated by an interaction of light and a metallic nanoparticle (NP) opens a wide horizon of studies in the different fields such as biosensing, health-care, tumor treatment, etc.. Nevertheless, the LSPR is very sensitive to interaction conditions: material, environment, geometry, polarization or angle of incidence.This investigation aims to fulfill a numerical and an experimental comparative study of the various size nanonparticles' LSPR evolution using different light sources and illumination types. The simulations are done with help of a commercial software from Lumerical Solutions Inc. based on the FDTD method. We verify the LSPR shifts caused by the well-known variations (size, geometry, environment changes). As a point source is used a vertical dipole placed in the vicinity of Ag NP. One may observe that there is LSPR shift for different distances between the source and NP. Moreover, the LSPR for dipole source varies from planewave illumination LSPR. We further find that there is LSPR shift for an horizontal dipole as well. The LSPR shift is quite intuitive for a dipole source depending on the distance between itself and NP, as we have coupled system. We demonstrate the electric field maps comparison of differently oriented dipoles and plane wave, which also can show the nature of the LSPR shift. At the current stage, our work shows promising results. For future we will do comparative studies via experiments and make the agreement with numerical simulations.

Abstract

International audience; Metal nanoparticles have attracted great scientific and technological interest in many application fields, mainly due to their ability to sustain Localized Surface Plasmon Polaritons (LSPP). Linear optical properties and LSPP resonances of metallic nanoparticles or nano-antennas have been well described, since decades, in the literature by extinction and/or scattering spectroscopies and by radiation patterns in direct or in Fourier space. However, much less is known on their non-linear optical properties, and on the role of LSPP resonances in the enhancement of these effects. Two-photon photoluminescence (TPPL) and second harmonic generation (SHG) are both prominent examples of nonlinear effects observed on metallic nanoparticles. Compared to the TPPL process, a third-order process which intrinsically relies on a high local optical field, SHG additionally requires materials with a high second order susceptibility and an inversion symmetry breaking. Such selection rules have to be considered in addition to the ‘plasmonic molecular hybridization’ model, in order to understand the SHG and the TPPL efficiencies in metallic dimers. In this study, we focused on the linear and nonlinear optical characterization of Au-Al heterodimers (Fig1). These metallic dimers have been fabricated by a two-step electron-beam lithography process where the diameters of the Au and Al nanoparticles have been independently varied, as well as the gap distance. The linear optical properties (single dimer scattering spectra) and the non-linear optical properties (SHG and TPPL spectra) have been compared to understand the main physical phenomena involved.

Abstract

International audience; Metallic nanoantennas with sub-wavelength dimensions exhibit usually strong plasmon resonances, which influence their optical properties dominantly. We have investigated the linear and non-linear optical effects from various plasmonic systems like nanoparticles, sharp tips and nanotriangles with either confocal optical microscopy or scanning near-field optical microscopy (SNOM). The linear optical properties of dimer antennas consisting of two Au nanospheres with a small gap in between are very commonly investigated. They are known to exhibit strong near field inside a small gap between the two plasmonically coupled single nanoobjects. Based on the gap-field generated by the plasmonic coupling, nonlinear effects like second harmonic generation (SHG) and two photon photoluminescence (2PPL) can be investigated. We choose arrays of Au homo- and hetero-dimers to study the influences of particle size and gap distance on the nonlinear polarisation properties of these dimer structures. Especially the angle resolved 2PPL and the SHG signals were measured and their different dependences on the electromagnetic near-field were discussed. In our recent study, we reported to use SNOM tips studying the plasmonic coupling between a sharp tip apex and the different positions of one single Au nanotriangle. We presented SHG and 2PPL spectroscopy and microscopy in this Au-Au gap mode with sub 30 nm optical resolution. To achieve a more precise and flexible control of the gap distance in the Au-Au dimer antenna especially at small distances of less than 5 nm, we will adopt a similar SNOM configuration where a sharp Au tip is positioned in the close proximity of a Au surface via sensitive shear-force feedback. By switching between the radial and azimuthal polarized doughnut modes, we will compare the dependence of the SHG and 2PPL intensity on the local near-field in the Au tip – Au substrate that is less than 5 nm wide.

Abstract

International audience; Metallic nanostructures exhibit fascinating linear and nonlinear optical properties once they are excited by appropriate incident light. Localized Surface Plasmons (LSPs) generated by a collective oscillation of electrons in the conduction band offer the possibility of enhancing and concentrating the electrical field in a subwavelength volume enabling the nanostructures to act similarly to antennas in the microwave or radiowave regime. The influences of LSP resonances on the linear optical properties of plasmonic nanoantennas, such as the scattering, the absorption, and the one-photon photoluminescence have been rigorously and systematically investigated. However, nonlinear optical processes in plasmonic nanoantennas, such as two-photon photoluminescence (TPL) and second harmonic generation (SHG), are still not fully understood. A comprehensive study of TPL and SHG from separated and connected gold nanodimers fabricated using an electron-beam-lithographic technique was conducted here. In particular, the influence of the gap size and nanodisc diameter on their nonlinear optical response is addressed in detail. Analyzing the nonlinear optical spectra and performing polarization resolved measurements by rotating the excitation field, using an experimental setup combining a femtosecond laser source with a parabolic mirror, we show that SHG and TPL exhibit a different behavior despite the fact that these two nonlinear optical processes have the same fundamental intensity dependence. The underlying physical mechanisms explaining the differences are revealed using a surface integral equation method for nonlinear computations. The different evolutions of SHG and TPL with the nanodimer geometry are due to their distinct physical natures, resulting in different coherence properties and specific rules for plasmon enhancement.

Abstract

International audience; Second Harmonic Generation (SHG) is well known to be a powerful imaging tool for background‐free and nondamaging live tissues investigation. Incidentally, field enhancements in plasmonic nanostructures are often exploited to effectively compensate for the lack of phase‐matching in confined volumes. Proper optimization of such phenomena may allow realizing biosensing platforms based on nanoscale nonlinear sources. Recently, we reported single‐crystalline gold nanoantennas working in the near‐infrared that show unprecedented SHG efficiency thanks to (i) a multi‐resonant response occurring at both the excitation and SH wavelength, (ii) a significant spatial overlap of the localized fields at the wavelengths of interest and (iii) a broken‐symmetry geometry to achieve dipole‐allowed SHG. The effective combination of these key features in a single plasmonic antenna, characterized by the absence of local defects, allowed for the optimization of SHG efficiency in a well‐controlled fashion. Here, by expanding the paradigm for SHG enhancement to extended metasurfaces of nanoantennas, we aim at realizing a nonlinear platform that can be easily integrated in standard biosensing devices, since it can be excited by a weakly‐focused light. To this purpose, using electron beam lithography (EBL), we developed a first prototypical device based on a 10x10 um2 array of closely‐packed L‐shaped antennas. We have characterized the nonlinear response of this device using a homemade confocal microscope equipped with a 0.7 numerical aperture (NA) objective (Nikon) working in epireflection, coupled to a 120 fs laser centered at 1550 nm. By comparing experiments and simulations, we found that in this device SHG is dominated by the plasmonic resonance of the antennas at the fundamental wavelength. When comparing the average SHG from the array with the signal from individual L‐shape nanoantennas, an enhancement of about 15‐20 times is found that, considering about 50 antennas under the illumination spot, implies a drop in the emission efficiency of the individual antennas. Indeed, FDTD simulations demonstrate that, while a single antenna has a directional emission peaking away from the sample normal, the square‐lattice array radiates only through the (0,0) diffraction order (i.e. normal to the sample). The effective second harmonic emission from the array is then the convolution between the single‐antenna radiation pattern and the array diffraction pattern. This effectively inhibits some of the SH radiation that would be emitted by the isolated nonlinear antennas, which gets dissipated in the array itself. The relatively high NA employed, used here to probe possible inhomogeneities in sample fabrication, allows one to efficiently collect SHG from both the array and the individual antennas. On the contrary, calculations show that using a NA as small as 0.2 all of the SHG from the individual antennas would be lost while more than 80% of the SHG emitted by the array could still be collected. This is achieved thanks to the grating effect of the array, which strongly confines the light emission into a very small solid angle. If properly optimized, this emission mode‐matching paradigm could lead to the implementation of simple filterless and objective‐free nonlinear biosensors.

Abstract

International audience; Metallic nanoantennas with sub‐wavelength dimensions exhibit usually strong plasmon resonances, which influence their optical properties dominantly. The linear optical properties of dimer antennas consisting of two gold nanoparticles with a small gap in between are very commonly investigated. They are known to exhibit strong electromagnetic hot spots inside a small gap between the two plasmonically coupled single nanoobjects. We have investigated the linear and non‐linear optical effects from various plasmonic systems like nanoparticles, sharp tips and nanotriangles with either confocal optical microscopy or scanning near‐field optical microscopy (SNOM). Towards the achievement of efficient plasmonic nanosources based on nonlinear effects, we choose arrays of gold homo‐ and hetero‐dimers to study the influence of electromagnetic hot spots on the second harmonic generation (SHG) and two photon photoluminescence (2PPL). We show that the generation of both signals is differently influenced by changing the dimer gap distances and particle sizes. We demonstrate that the nonlinear optical signal intensity provides no direct information about the external fundamental near‐field distributions and intensities around plasmonic nanostructures, despite the fact that these two distributions are closely related to each other. We show that the SHG and 2PPL intensities as well as the spectral position of the 2PPL emission can be selectively tuned by changing the particle material and the dimer geometry. To investigate nonlinear optical signals from a narrow gap of less than 5 nm, we combine an ultrafast laser system with SNOM. Based on the sensitive shear‐force or tunnelling current feedback, we are able to control the gap distance accurately and to study the nonlinear optical processes in extremely narrow gaps that are difficult to be fabricated via conventional lithographical methods. Furthermore, using this combination the nonlinear optical signal generation from different positions of a plasmonic nanostructure can be resolved with an optical resolution of less than 30 nm.

Abstract

International audience; The coupling between the surface plasmon resonance of metallic nanoparticles and the emission band of quantum dots can lead to the enhancement or the quenching of the fluorescence of the quantum dots. The result depends on the distance between the nanoparticles and the quantum dots, and the spectral position of the resonance. The purpose of this work is to design a device which could allow to pilot optically the crossing between enhancement and quenching by combining optic molecular switches (photochromic molecules) to the coupling system metallic nanoparticles / quantum dots. The transition of a photochromic molecule from a colorless state (A) to a color state (B) is very fast (ps) and lead to an important modification of the refractive index.

Abstract

International audience; The use of silicon nanocrystals (SiNC) in optoelectronic devices has risen from a decade thanks to the discovery of photoluminescence in porous silicon in 1991. However SiNCs exhibit a low quantum yield, which prevent from currently using them in optoelectronic devices. This problem can be bypassed thanks to the use of localized surface plasmons (LSP). Indeed LSPs can modify emitters’ photoluminescence by changing the optical local density of states and/or increasing the local excitation field. Numerous studies have been realized with different emitters but the study of LSP coupled with SiNC is scarce. Seminal studies by Biteen and coworkers have paved the way for increasing SiNCs’ performances with LSPs. In these preliminary works only the SiNCs’ emission wavelength was coupled to LSPs. In this work, we present a study where LSPs resonances are coupled simultaneously with the absorption and emission wavelengths of SiNCs. Our original fabrication method gives us the control of all the geometrical parameters that modify the SiNCs-LSPs coupling. The use of nanorods with different shapes and metals allows us to have two plasmon modes. One is located at the SiNC’s absorption wavelength and the other is located at the SiNC’s emission wavelength. The SiNC’s photoluminescence enhancement is thus due to two physical phenomena. To understand these phenomena, we study the influence on SiNC’s photoluminescence intensity, polarization and spatial redirection. We also extract the SiNCs’ radiative quantum yield enhancement in presence of these rods.
