“…The implementation of such complex RWGs now calls for efficient design and fabrication methods in order to enable their transfer toward the photonics industry. Thanks to these developments in mastering nanostructures and benefitting from established large throughput replication processes, RWGs are promising building blocks for other emerging paradigms, such as wavefront control and light routing metasurfaces with high coupling and small confinement between different unit cells. RWG properties can be used as well on 2D structures to make photonic crystals relying on leaky guided modes as analyzed by Fan or used by Wang and Matsui .…”

Resonant waveguide gratings (RWGs), also known as guided mode resonant (GMR) gratings or waveguide‐mode resonant gratings, are dielectric structures where these resonant diffractive elements benefit from lateral leaky guided modes from UV to microwave frequencies in many different configurations. A broad range of optical effects are obtained using RWGs such as waveguide coupling, filtering, focusing, field enhancement and nonlinear effects, magneto‐optical Kerr effect, or electromagnetically induced transparency. Thanks to their high degree of optical tunability (wavelength, phase, polarization, intensity) and the variety of fabrication processes and materials available, RWGs have been implemented in a broad scope of applications in research and industry: refractive index and fluorescence biosensors, solar cells and photodetectors, signal processing, polarizers and wave plates, spectrometers, active tunable filters, mirrors for lasers and optical security features. The aim of this review is to discuss the latest developments in the field including numerical modeling, manufacturing, the physics, and applications of RWGs. Scientists and engineers interested in using RWGs for their application will also find links to the standard tools and references in modeling and fabrication according to their needs.

“…Compared to the total transparencies shown in Figs. 2, 3 and 5 for metasurfaces, it is more challenging to achieve the same with metagratings, as it is required to significantly suppress or eliminate three out-coupling channels rather than only Compared to previous studies for large-angle high-efficiency beam steering relying an asymmetric unit cells , 30,31,33 the results in Figs. 6 and 7 clearly demonstrate that asymmetric antennas (like the one shown in Ref.…”

We study optical wave manipulations through high-index dielectric metalattices in both diffractionless metasurface and diffractive metagrating regimes. It is shown that the collective lattice couplings can be employed to tune the excitation efficiencies of all electric and magnetic multipoles of various orders supported by each particle within the metalattice. The interferences of those adjusted multipoles lead to highly asymmetric angular scattering patterns that are totally different from those of isolated particles, which subsequently enables flexible beam manipulations, including perfect reflection, perfect transmission and efficient large-angle beam steering. The revealed functioning mechanism of manipulated interplays between lattice couplings and multipolar interferences can shed a new light on both photonic branches of metasurfaces and metagratings, which can potentially inspire many advanced applications related to optical beam controls.

“…We emphasize here that many optical properties of metalattices have already been discussed in literature, including perfect transmission [145][146][147][148][149][150][151][152], perfect reflection [147,148,151,[153][154][155][156][157][158], high-order diffraction management [159,160], and perfect absorption [135,137,148,161,162]. However, for most cases no explicit connections between those functionalities and the generalized Kerker effects have been established.…”

The original Kerker effect was introduced for a hypothetical magnetic sphere, and initially it did not attract much attention due to a lack of magnetic materials required. Rejuvenated by the recent explosive development of the field of metamaterials and especially its core concept of optically-induced artificial magnetism, the Kerker effect has gained an unprecedented impetus and rapidly pervaded different branches of nanophotonics. At the same time, the concept behind the effect itself has also been significantly expanded and generalized. Here we review the physics and various manifestations of the generalized Kerker effects, including the progress in the emerging field of meta-optics that focuses on interferences of electromagnetic multipoles of different orders and origins. We discuss not only the scattering by individual particles and particle clusters, but also the manipulation of reflection, transmission, diffraction, and absorption for metalattices and metasurfaces, revealing how various optical phenomena observed recently are all ubiquitously related to the Kerker's concept.
