Halide perovskites have become a versatile platform not only for optoelectronic devices but also for modern optics and nanophotonics. Perovskite nano‐ and micro‐particles, metasurfaces, and photonic crystals demonstrate their applicability for directional enhanced photo‐ and electro‐luminescence, lasing, as well as for improving the performance of optoelectronic devices. However, ionic nature makes perovskites water soluble, while their high sensitivity to diverse chemicals complicates their patterning toward the formation of functional, high‐quality nanostructures. Here, recent progress on emerging laser technologies for processing and nanopatterning of halide perovskites, as well as their applications in designing advanced light‐emitting systems and controlling light at the nanoscale is overviewed. Special emphasis is made on the processes underlying the interaction of laser radiation with perovskites to disclose new avenues for their surface and volume modification with ultra‐high precision and a high degree of material's property control.

“…We conclude from equation (44) that the selection rules are independent on the harmonic order N. Therefore, we can write that the transmission and reflection amplitudes are equal on both sides of the metasurface upon changing from the left-to right-polarization and vice versa…”

“…Chiroptical activity in nonlinear metastructures and metasurfaces has been a topic of very intense studies [40][41][42][43][44]. Analogous to linear phenomena, the enhancement of nonlinear chiroptical effects beyond the constraints of inherent material responses can be realized through breaking macroscopic symmetries of metasurface lattice and meta-atoms.…”

We generalize the concept of optical scattering matrix (S-matrix) to characterize harmonic generation and frequency mixing in planar metasurfaces in the limit of undepleted pump approximation. We show that the symmetry properties of such nonlinear S-matrix are determined by the metasurface symmetries at the macroscopic and microscopic scale.. We demonstrate that for description of degenerate frequency mixing processes such as optical harmonic generation, the multidimensional S-matrix can be replaced with a reduced two-dimensional S-matrix. We show that for metasurfaces possessing specific point group symmetries, the selection rules determining the transformation of the reduced nonlinear S-matrix are simplified substantially and can be expressed in a compact form. We apply the developed approach to analyse chiral harmonic generation in nonlinear metasurfaces with various symmetries including rotational, inversion, in-plane mirror, and out-of-plane mirror symmetries. For each of those symmetries, we confirm the results of the developed analysis by full-wave numerical calculations. We believe our results provide a new paradigm for engineering nonlinear optical properties of metasurfaces which may find applications in active and nonlinear optics, biosensing, and quantum information processing.

“…Recent advances in nanotechnologies have facilitated the development of ultra-thin single-layer dielectric metasurfaces, where optical nano-resonators can enhance and tailor the nonlinear interactions with functionalities beyond the capabilities of traditional bulky crystals [7]- [11]. To generate optical resonances, previous metasurface designs have often relied on semianalytical approaches in the limiting cases of Mietype modes for individual nanoresonators [12]- [18], or bound state in the continuum resonances [19]- [26].…”

High-efficiency sum frequency generation from inverse designed metasurfaces

Sum frequency generation is the process in which two incoming photons are converted into an outgoing photon of higher energy. This process is highly inefficient, and therefore requires either large interaction distances in bulky crystals, or large field concentrations in the non-linear materials. Metasurfaces are one such platform to generate extreme field enhancements with resonant processes. In this work, we use topology optimisation to design metasurfaces that exhibit increase high efficiency sum frequency generation, as well as the ability to tailor the generated polarisation.
