“…In the following we explain these observations by applying our modal approach to a structure similar to that of 58 . We consider an array of gold SRRs arranged in a square lattice in the yz plane (one unit cell is depicted in the inset of Fig.…”

“…Recently several experimental and theoretical efforts have been carried out in this field 27,[50][51][52][53][54][55][56][57] . One of the latest experiments is reported in 58 , where SHG spectroscopy on 2D arrays of gold split-ring resonators (SRR) was studied. It was found that when the frequency of the incident EM field is close to the fundamental plasmonic resonance of the metamaterial, the frequency dependence of the SHG signal can be nearly described by a Lorentzian shaped curve.…”

“…Note that the (2,e) mode has a damping loss much smaller than that of the (1,e) mode, a phenomenon that has been observed numerically in 59 . As in 58 we choose the incident frequency quite close to ω 0 . Consequently only the lowest-order odd mode contributes significantly to the linear fields, i.e.,…”

We apply a rigorous eigenmode analysis to study the electromagnetic properties of linear and weakly nonlinear metamaterials. The nonlinear response can be totally described by the linear eigenmodes when weak nonlinearities are attributed to metamaterials. We use this theory to interpret intrinsic second-harmonic spectroscopy on metallic metamaterials. Our study indicates that metamaterial eigenmodes play a critical role in optimizing a nonlinear metamaterial response to the extent that a poorly optimized modal pattern overwhelms the widely recognized benefits of plasmonic resonant field enhancements.

“…The nonlinear susceptibility tensors of the metasurfaces can be easily tailored by the structural design, and the spin state and spectra of the nonlinearly converted light beam can be modulated. Typical examples includes L-shaped gold nanoparticle [142,143], T-shaped nanoparticle [144], split-ring resonator (SPR) with electric or magnetic dipole resonance [145][146][147], and silver triangular nanoprisms and nanoholes [148,149]. A symmetry-breaking metasurface not only significantly enhances its nonlinear optical response but also shows strong spin-selectivity in the nonlinearly generated light [150].…”

Optical spin-Hall effect (OSHE) is a spindependent transportation phenomenon of light as an analogy to its counterpart in condensed matter physics. Although being predicted and observed for decades, this effect has recently attracted enormous interests due to the development of metamaterials and metasurfaces, which can provide us tailor-made control of the light-matter interaction and spin-orbit interaction. In parallel to the developments of OSHE, metasurface gives us opportunities to manipulate OSHE in achieving a stronger response, a higher efficiency, a higher resolution, or more degrees of freedom in controlling the wave front. Here, we give an overview of the OSHE based on metasurface-enabled geometric phases in different kinds of configurational spaces and their applications on spin-dependent beam steering, focusing, holograms, structured light generation, and detection. These developments mark the beginning of a new era of spin-enabled optics for future optical components.

“…Compared to bulk nonlinear crystals, nonlinear optical metamaterials provide new possibilities for the integration of nonlinear optical functionalities into nanophotonic chips. Several methods have been demonstrated to achieve large effective nonlinear susceptibilities such as poling in polymers [2], alternating stacking of germaniumdoped and undoped poled-silica layers [3], and exploiting metallic nanostructures with noncentrosymmetric geometries [4][5][6][7][8][9]. Lee et al [10] also utilized inter-subband transitions in multi-quantum well semiconductor heterostructures at infrared wavelengths.…”

Nanolaminate metamaterials recently attracted a lot of attention as a novel second-order nonlinear material that can be used in integrated photonic circuits. Here, we explore theoretically and numerically the opportunity to enhance the nonlinear response from such nanolaminates by exploiting Fano resonances supported in grating-coupled waveguides. The enhancement factor of the radiated second harmonic signal compared to a flat nanolaminate can reach values as large as 35 for gold gratings and even 7000 for MgF 2 gratings. For the MgF 2 grating, extremely high-Q Fano resonances are excited in such all-dielectric system that result in strong local fields in the nonlinear waveguide layer to boost the nonlinear conversion. A significant portion of the nonlinear signal is also strongly coupled to a dark waveguide mode, which remains guided in the nanolaminate. The strong excitation of a dark mode at the second harmonic frequency provides a viable method for utilizing second-order nonlinearities for light generation and manipulation in integrated photonic circuits.
