“…As a consequence, nonlinear light-emitting metasurfaces allow for easier wavefront shaping [320,321] than their fluorescence-based cousins. Finally, nonlinear absorption processes resulting in multiphoton-induced PL should be mentioned, for which resonant nanoparticles [322] and metasurfaces [323] can greatly enhance the excitation rate if the pump laser frequency coincides with the nanostructure resonances. -Raman scattering: The electromagnetic field enhancement provided by metasurfaces can furthermore be exploited in surface-enhanced Raman spectroscopy (SERS), where light at new frequencies is emitted via inelastic scattering of photons by molecules.…”

Photonic metasurfaces, that is, two-dimensional arrangements of designed plasmonic or dielectric resonant scatterers, have been established as a successful concept for controlling light fields at the nanoscale. While the majority of research so far has concentrated on passive metasurfaces, the direct integration of nanoscale emitters into the metasurface architecture offers unique opportunities ranging from fundamental investigations of complex light-matter interactions to the creation of flat sources of tailored light fields. While the integration of emitters in metasurfaces as well as many fundamental effects occurring in such structures were initially studied in the realm of nanoplasmonics, the field has recently gained significant momentum following the development of Mie-resonant dielectric metasurfaces. Because of their low absorption losses, additional possibilities for emitter integration, and compatibility with semiconductor-based light-emitting devices, all-dielectric systems are promising for highly efficient metasurface light sources. Furthermore, a flurry of new emission phenomena are expected based on their multipolar resonant response. This review reports on the state of the art of light-emitting metasurfaces, covering both plasmonic and all-dielectric systems.

“…Recently, meta-optics based on halide perovskites nanostructures [1] has attracted a lot of attention due to its numerous applications in structural coloring, [2,3] enhanced luminescence, [4] tunable meta-pixels, [5,6] optical encoding, [7,8] lasing, [9][10][11] speckle-free imaging, [12] and photovoltaics. [13] Various applications of optoelectronic devices based on perovskites require suppression of reflection to achieve higher transparency in the sub-bandgap spectral range, but parasitic reflection limits the efficiency of photovoltaics devices, smart windows, and active glasses.…”

Meta-optics based on optically resonant dielectric nanostructures is a rapidly developing research field with many potential applications. Halide perovskite metasurfaces have emerged recently as a novel platform for meta-optics, and they offer unique opportunities for control of light in optoelectronic devices. Here, the generalized Kerker conditions are employed to overlap electric and magnetic Mie resonances in each meta-atom of MAPbBr 3 perovskite metasurface, and broadband suppression of reflection down to 4% is demonstrated. Furthermore, it is revealed that metasurface nanostructuring is also beneficial for the enhancement of photoluminescence. These results may be useful for applications of nanostructured halide perovskites in photovoltaics and semi-transparent multifunctional metadevices where reflection reduction is important for their high efficiency.

“…The nanostructures were fabricated within the MAPbBr 3 perovskite films with a combined process of electron beam lithography and inductively coupled plasma etching (see "Methods"). In contrast to the previous reports 4, 25,45 , the etching gas Cl 2 is replaced with a mixture of H 2 and Ar. This change brings two improvements.…”

Lead halide perovskite microlasers have been very promising for versatile optoelectronic applications. However, most perovskite microlasers are linearly polarized with uniform wavefront. The structured laser beams carrying orbital angular momentum have rarely been studied and the applications of perovskites in next-generation optical communications are thus hindered. Herein, we experimentally demonstrate the perovskite vortex microlasers with highly directional outputs and well−controlled topological charges. High quality gratings have been experimentally fabricated in perovskite film and the subsequent vertical cavity surface emitting lasers (VCSELs) with divergent angles of 3o are achieved. With the control of Archimedean spiral gratings, the wavefront of the perovskite VCSELs has been switched to be helical with topological charges of q = −4 to 4. This research is able to expand the potential applications of perovskite microlasers in hybrid integrated photonic networks, as well as optical computing.
