“…We consider finite and infinite (N = ∞) 2D periodic arrays of identical NPs. In both cases, we compare respective extinction efficiencies, Q ext , which is in line with previous similar studies [25,29,30,33]. The arrays are illuminated from the top by the plane wave with normal incidence along the Z axis positive direction and polarization along the X axis; see Figure 1.…”

“…In all of these frameworks, closed-form analytical solutions are available for the extinction, scattering and absorption cross sections for infinite periodic structures. CLRs in finite arrays are almost exclusively studied within the coupled dipole approximation: for plasmonic systems, taking into account only ED interactions [23][24][25][26][27][28][29][30], and for all-dielectric arrays, taking into account ED and MD interactions [31][32][33][34]. Recent works on CLRs suggest a great promise of multipolar CLRs, obviously in arrays of high-index NPs [35] since such NPs support a richer variety of multipolar modes [36] compared to plasmonic counterparts.…”

Multipolar Lattice Resonances in Plasmonic Finite-Size Metasurfaces

Collective lattice resonances in regular arrays of plasmonic nanoparticles have attracted much attention due to a large number of applications in optics and photonics. Most of the research in this field is concentrated on the electric dipolar lattice resonances, leaving higher-order multipolar lattice resonances in plasmonic nanostructures relatively unexplored. Just a few works report exceptionally high-Q multipolar lattice resonances in plasmonic arrays, but only with infinite extent (i.e., perfectly periodic). In this work, we comprehensively study multipolar collective lattice resonances both in finite and in infinite arrays of Au and Al plasmonic nanoparticles using a rigorous theoretical treatment. It is shown that multipolar lattice resonances in the relatively large (up to 6400 nanoparticles) finite arrays exhibit broader full width at half maximum (FWHM) compared to similar resonances in the infinite arrays. We argue that our results are of particular importance for the practical implementation of multipolar lattice resonances in different photonics applications.

“…[17,19,207] To overcome this limitation, Odom's group has developed a series of nanolasers using organic dye molecules (such as IR-140) as gain materials. [208][209][210][211][212] In this configuration, plasmonic arrays are sandwiched between the dye layer and a coverslip (Figure 7c) to achieve the effective excitation of nanolasing at room temperature. [204] While most of their lasing emissions are pumped with the ultrafast pulse laser to compensate the losses, the possible photoinduced fluorescence bleaching may compromise their long-term stability under a strong pump radiation.…”

can efficiently couple light into nanostructures and confine light below diffraction limit. [8,9] With these properties, plasmonics have found important applications in various fields such as plasmonic sensing, [10][11][12][13] plasmon-enhanced spectroscopies, [14][15][16] plasmonic nanolasing, [17][18][19] and perfect light absorption. [20,21] The optical performances of plasmonic nanostructures are highly dependent on the resonance modes that they support. Generally, there are two fundamental surface plasmonic modes: localized surface plasmon resonance (LSPR) and propagating surface plasmon polaritons (SPP). [22,23] LSPR can be observed on metal nanoparticles. [22,24,25] However, the strong radiative damping of metal nanoparticles results in broad resonant spectra, severely limiting the applications of metal nanoparticles in fields such as plasmonic sensing and nanolasing. [26,27] SPP is usually generated at the interface between metal and dielectric with the assistance of a high refractive index prism or by constructing a grating structure. [23,28,29] The near-field decay length of SPP mode is 40-50 times larger than that of LSPR mode. [23] Therefore, SPP structures usually provide higher bulk sensitivity when used for plasmonic sensing. [23] However, it is difficult to achieve a flexible tuning of SPP mode only by above configurations. In addition, single resonance mode also greatly limits the applications of the devices.According to the plasmon hybridization theory, coupling of different resonance modes can endow plasmonic nanostructures with richer optical properties and thereby improve their performance and broaden their application fields. [30][31][32] Metallic plasmonic arrays have been demonstrated to be a powerful platform for the simultaneous excitation of the above two basic types of plasmonic modes. [33,34] In addition, they can also support many other types of resonance modes such as Fabry-Pérot (F-P) cavity mode, surface lattice resonance (SLR), and plasmonic Fano resonance due to the flexibility in structure design. [32,[35][36][37][38] These modes together give the nanostructured plasmonic arrays with attractive performance unattainable by using individual LSPR or SPP mode. Benefited from the abundant optical properties, nanostructured metallic plasmonic arrays can be utilized in a fashion of "device-by-design." For example, for plasmonic sensing, a plasmonic array with a narrow spectrum can be fabricated for an excellent sensing performance; [23,26] while for surface-enhanced Raman spectroscopy (SERS) detection, a plasmonic array with a relatively broad spectrum is needed to achieve local field enhancement and radiative enhancement simultaneously. [39,40] Therefore, the investigation The vast development of nanofabrication has spurred recent progress for the manipulation of light down to a region much smaller than the wavelength. Metallic plasmonic array structures are demonstrated to be the most powerful platform to realize controllable light-matter interactions and have found wide application...

“…Thus, the lasing signal of BIC should not be expected to be emitted. However, the lasing signal was detected in the experiment due to the artifacts produced during the fabrication process (Figure S2, Supporting Information) and the effects of noninfinite arrays [ 66 ] (Figure S3, Supporting Information). The defects in the structures can be observed in the optical images in Figure 4f.…”

Bound states in the continuum (BICs) have attracted considerable research attention due to their infinite quality factor (Q‐factor) and extremely localized fields, which drastically enhances light–matter interactions and yields high potential in topological photonics and quantum optics. In this study, the room temperature directional lasing normal to a BIC metasurface is demonstrated with hybrid surface lattice resonances. Compared to the plasmonic nanolasers, the BIC metasurface lasers possess directional radiation and a larger emission volume. The high Q‐factor resonance of BIC metasurface overcomes the limitation of a large mode volume in achieving low‐threshold lasing. In addition, a design rule is proposed to prevent the occurrence of wavelength shift when the Q‐factor changes; thus, the lasing thresholds for different BIC metasurfaces can be compared. In this work, the high localization ability of BICs is used to achieve the low lasing threshold (1.25 nJ) at the room temperature. The “light in–light out” diagram of the aforementioned laser based on simulations and experiments exhibits a large spontaneous emission coupling factor (β = 0.9) and the S‐curve. The device developed in this study can be used in various applications, such as quantum emitters, optical sensing, nonlinear optics, and topological states engineering.
