Abstract
Many outstanding properties of halide perovskites provided their applications in optoelectronics. Perovskite films demonstrate outstanding nonlinear properties with large optical nonlinearities comparable to the nonlinear constants of conventional semiconductor materials. Meanwhile, nonlinear properties can be enhanced by the metaphotonic approach. Here we demonstrate a two-order enhancement of fifth-harmonic generation in halide perovskite nonlocal metasurfaces due to high-quality resonance at the generated harmonic wavelength in the visible frequency range.
