“…More recent work has involved looking at the effect that the number of particles that comprise an array has on the SLR [16], while Zhou and Odom explored out-of-plane resonances [17]. SLRs associated with metal nanoparticle arrays are also interesting due to the way their modes interact with emissive species such as fluorescent molecules, both with regard to light emission [18], and with regard to strong coupling between lattice resonances and quantum emitters [19,20]. Metal nanoparticle arrays are important in plasmonic metamaterials [21], and SLRs have been explored in the context of topological metamaterials [22].…”

Arrays of metallic particles may exhibit optical collective excitations known as surface lattice resonances (SLRs). These SLRs occur near the diffraction edge of the array and can be sharper than the plasmon resonance associated with the isolated single particle response. We have fabricated and modeled arrays of silver nanoparticles of different geometries. We show that square, hexagonal, and honeycomb arrays show similar SLRs; no one geometry shows a clear advantage over the others in terms of resonance linewidth. We investigate the nature of the coupling between the particles by looking at rectangular arrays. Our results combine experiment and modeling based on a simple coupled-dipole model.

“…SLRs have been investigated in a number of contexts including: sensing [22], strong coupling between SLRs and molecular transitions [23,24] and lasing [25,26]. The work we report here is part of an exploration into the SLRs supported by square arrays of metallic dimers, i.e.…”

Abstract. We investigate the optical response of square arrays of metallic nanoparticles where each lattice site is occupied by two particles, a dimer. In particular we examine the surface lattice resonances arising in these structures when the inplane dipole moments associated with the plasmon modes of the nanoparticles couple together. The addition of a second particle to the basis leads to a more complex optical response, one that is anisotropic in the plane of the array. Extinction spectra are recorded at normal incidence for different orientations of the incident electric field. We compare our experimentally derived data with those from a coupled-dipole model. We show how the separation between the particles that comprise the dimer helps determine the overall response of the system.

“…Recently, delocalized electromagnetic modes supported by metal surfaces (surface plasmon polaritons) or periodic arrays of metallic nanoparticles [surface lattice resonances (SLRs) [8][9][10][11]] have been shown to strongly couple with localized emitters [12][13][14][15][16][17][18][19]. The strong coupling in these plasmonic systems involves a large number N of emitters.…”

We study spatial coherence properties of a system composed of periodic silver nanoparticle arrays covered with a fluorescent organic molecule (DiD) film. The evolution of spatial coherence of this composite structure from the weak to the strong coupling regime is investigated by systematically varying the coupling strength between the localized DiD excitons and the collective, delocalized modes of the nanoparticle array known as surface lattice resonances. A gradual evolution of coherence from the weak to the strong coupling regime is observed, with the strong coupling features clearly visible in interference fringes. A high degree of spatial coherence is demonstrated in the strong coupling regime, even when the mode is very excitonlike (80 %), in contrast to the purely localized nature of molecular excitons. We show that coherence appears in proportion to the weight of the plasmonic component of the mode throughout the weak-to-strong coupling crossover, providing evidence for the hybrid nature of the normal modes.
