“…In consequence of this effect, excessive electrical fields arise on the surface, which are very sensitive toward changes of the lattice spacing and the dielectric surrounding . Since the first experimental realization in 2008 by the groups of Grigorenko and Barnes, plasmonic SLRs have been shown in a variety of applications such as ultranarrow band absorbers, nonlinear field enhancement, strong coupling to dyes, and engineering of nanolasers …”

Noble metal nanoparticles can absorb incident light very efficiently due to their ability to support localized surface plasmon resonances (LSPRs), collective oscillations of the free electron cloud. LSPRs lead to strong, nanoscale confinement of electromagnetic energy which facilitates applications in many fields including sensing, photonics, or catalysis. In these applications, damping of the LSPR caused by inter‐ and intraband transitions is a limiting factor due to the associated energy losses and line broadening. The losses and broad linewidth can be mitigated by arranging the particles into periodic lattices. Recent advances in particle synthesis, (self‐)assembly, and fabrication techniques allow for the realization of collective coupling effects building on various particle sizes, geometries, and compositions. Beyond assemblies on static substrates, by assembling or printing on mechanically deformable surfaces a modulation of the lattice periodicity is possible. This enables significant alteration and tuning of the optical properties. This progress report focuses on this novel approach for tunable spectroscopic properties with a particular focus on low‐cost and large‐area fabrication techniques for functional plasmonic lattices. The report concludes with a discussion of the perspectives for expanding the mechanotunable colloidal concept to responsive structures and flexible devices.

“…Since larger Q-factor values imply higher local fields, especially nonlinear lightmatter interactions can be expected to be considerably enhanced near SLRs [13]. But so far, very little work has been conducted to systematically study the possibilities of utilizing periodic arrays of nanoparticles and SLRs for enhancing nonlinear optical processes [15][16][17][18].…”

Using surface lattice resonances to engineer nonlinear optical processes in metal nanoparticle arrays

et al. 2018

Collective responses of localized surface plasmon resonances, known as surface lattice resonances (SLRs) in metal nanoparticle arrays, can lead to high quality factors (∼100), large local-field enhancements and strong light-matter interactions. SLRs have found many applications in linear optics, but little work of the influence of SLRs on nonlinear optics has been reported. Here we show how SLRs could be utilized to enhance nonlinear optical interactions. We devote special attention to the sum-frequency, difference-frequency, and third-harmonic generation processes because of their potential for the realization of novel sources of light. We also demonstrate how such arrays could be engineered to enhance higher-order nonlinear optical interactions through cascaded nonlinear processes. In particular, we demonstrate how the efficiency of third-harmonic generation could be engineered via cascaded second-order responses.

“…Despite this common belief, this is not a fundamental limitation, since utilization of SLRs can result in spectral features with remarkably narrow linewidths [12,38,39]. In spite of these opportunities, only a few reports exist where SLRs have been used to enhance nonlinear responses of metasurfaces [40][41][42].…”

Less Is More: Enhancement of Second-Harmonic Generation from Metasurfaces by Reduced Nanoparticle Density

et al. 2018

We investigate optical second-harmonic generation (SHG) from metasurfaces where noncentrosymmetric V-shaped gold nanoparticles are ordered into regular array configurations. In contrast to expectations, a substantial enhancement of the SHG signal is observed when the number density of the particles in the array is reduced. More specifically, by halving the number density, we obtain over 5-fold enhancement in SHG intensity. This striking result is attributed to favorable interparticle interactions mediated by the lattice, where surface-lattice resonances lead to spectral narrowing of the plasmon resonances. Importantly, however, the results cannot be explained by the improved quality of the plasmon resonance alone. Instead, the lattice interactions also lead to further enhancement of the local fields at the particles. The experimental observations agree very well with results obtained from numerical simulations including lattice interactions.
