Halide perovskite is a promising candidate for high-performance and ultra-compact light emitters which are the core of the next-gen display technology. Despite various µ-Perovskite-LED array design availability, achieving finely controlled emission patterns, by implementing nanopatterns on the active media (metasurfaces), is a key challenge. In this work, we demonstrate a design and fabrication procedure for perovskite metasurface LED whose optical properties are controlled by nanopatterning. The obtained results pave the way for radiation control in perovskite LEDs and micro-LEDs.
