“…A macroscopic description of the nonlinear response from arrays of noncentrosymmetric nanoparticles is based on the effective multipolar tensors [131][132][133][134]. In particular, the magnetic dipole and electric quadrupole contributions were experimentally identified in the nonlinear emission of L-shape gold nanoparticles through asymmetry of the generated SH field intensity measured in transmission and reflection [135].…”

Nonlinear nanophotonics is a rapidly developing field with many useful applications for a design of nonlinear nanoantennas, light sources, nanolasers, sensors, and ultrafast miniature metadevices. A tight confinement of the local electromagnetic fields in resonant photonic nanostructures can boost nonlinear optical effects, thus offering versatile opportunities for subwavelength control of light. To achieve the desired functionalities, it is essential to gain flexible control over the near-and far-field properties of nanostructures. Thus, both modal and multipolar analyses are widely exploited for engineering nonlinear scattering from resonant nanoscale elements, in particular for enhancing the near-field interaction, tailoring the far-field multipolar interference, and optimization of the radiation directionality. Here, we review the recent advances in this recently emerged research field ranging from metallic structures exhibiting localized plasmonic resonances to hybrid metal-dielectric and alldielectric nanostructures driven by Mie-type multipolar resonances and optically-induced magnetic response.

“…These properties of the SHG response confirm the suitability of the effective medium treatment of the metamaterial for this nonlinear process. Therefore, the considerations of the symmetry of the second-order susceptibility tensor χ (2) for an in-plane isotropic continuous film can be applied for the studied structure 23,24 , and the SHG response of the metamaterial can be considered as for a nonlinear medium with the dipole axis oriented perpendicularly to the film surface. Figure 3 shows the SHG intensity spectrum measured when the wavelength of the s-polarized pump beam was scanned in the range 730-830 nm for a 20…”

“…In particular, Zdanowicz et al attributed asymmetric SHG from L-shaped gold nanoparticles to the nonlinear interference between second-order electric, magnetoelectric, and quadrupolar tensors [15]. This recent progress suggests that artificial media, or metamaterials, constructed from arrays of nanoparticles might provide a means to tailor the effective nonlinear susceptibilities.…”

When both electric and magnetic mechanisms contribute to a particular nonlinear optical process, there exists the possibility for nonlinear interference, often characterized by constructive or destructive interference in the radiation pattern of harmonics and mix waves. However, observation of a significant effect from nonlinear interference requires careful balancing of the various contributions. For this purpose, we propose an artificial metamaterial, using the formalism of nonlinear magnetoelectric coupling to simultaneously engineer the nonlinear polarization and magnetization. We confirm our predictions of nonlinear interference with both simulations and experiment, demonstrating unidirectional wave mixing in two microwave metamaterials. Our results point toward an ever wider range of nonlinear properties, in which nonlinear interference is just one of many potential applications.
