“…Recently, a sandwich architecture based on two Al NP metasurfaces and a liquid gain layer has shown white-light lasing. 243 The device consisted of two Al NP lattices on two separate quartz substrates separated by a droplet of mixed dye solution (Figure 20b). Because of the micrometer-scale spatial separation of the two metasurfaces, interlayer coupling is negligible.…”

This Review focuses on the integration of plasmonic and dielectric metasurfaces with emissive or stimuli-responsive materials for manipulating light–matter interactions at the nanoscale. Metasurfaces, engineered planar structures with rationally designed building blocks, can change the local phase and intensity of electromagnetic waves at the subwavelength unit level and offers more degrees of freedom to control the flow of light. A combination of metasurfaces and nanoscale emitters facilitates access to weak and strong coupling regimes for enhanced photoluminescence, nanoscale lasing, controlled quantum emission, and formation of exciton–polaritons. In addition to emissive materials, functional materials that respond to external stimuli can be combined with metasurfaces to engineer tunable nanophotonic devices. Emerging metasurface designs including surface-functionalized, chemically tunable, and multilayer hybrid metasurfaces open prospects for diverse applications, including photocatalysis, sensing, displays, and quantum information.

“…After the first concept of a plasmonic nanolaser had been proposed based on amplifying the LSP mode of a metal nanoparticle, [41,239] a lot of plasmonic lasers were realized using metal-insulator films [240][241][242] and arrays of metal nanoparticles. [156,[243][244][245] Monolayer TMDs have direct bandgaps and an exciton binding energy larger than the thermal energy at room-temperature. These advantages make the monolayer TMDs behave as a promising gain material for room-temperature lasing based on the exciton transition.…”

The SLR wavelength (λ SLR ) is readily changed by modifying the lattice period or surrounding refractive index, and the utility of this property has been shown in examples such as tunable lasers, , white lasers, color generation, strain sensors, , and refractive index sensors . Additionally, the near-field distribution of the electromagnetic (EM) fields and the far-field scattering from the lattice can be controlled by changing the number − and type , of structures used within the unit cell, as well as the periodicity of the lattice. ,,, …”

Periodic arrays of metal nanostructures can host lattice resonances, which arise from coherent scattering between many structures in the lattice. These resonances are highly tunable with high quality factors and have found applications in lasers, biosensors, and metaoptics. Using bipartite lattices that have two structures per unit cell allows the sub/superradiant nature of the lattice resonances to be controlled, giving smaller line widths, multiple resonances, and resilience to finite-sized effects. In this work, we investigate the spectral and near-field properties of surface lattice resonances supported by asymmetric bipartite lattices. We show that these lattices host hybridized dipole resonances that can be elliptically polarized due to the overlap of two orthogonal resonances. We also show that, due to this, these resonances have a nontrivial phase relationship between orthogonal lattice resonances, which could expand the application of surface lattice resonance to vector and vortex beam generation with nonlinear polarizations. We demonstrate how these resonances can be controlled by changing the separation of the structures. Furthermore, we investigate the effect of changing the structure sizes and show that bound states in the continuum can be achieved when the structure sizes are equal.
