Abstract: Spatial localization of light requires high- Q cavities or disorder, yet the wave nature of light may open novel opportunities for the enhanced confinement of light via interference effects. Here we employ the basic concepts of the recently emerged field of Mie-tronics as a powerful tool to achieve the hybridization of different resonances in finite arrays of resonators to boost the Q factors with in-plane multiple scattering. When applied to photonic moiré structures, our approach yields a giant enhancement of the Purcell factor via twist-induced coupling between degenerate collective modes. Our findings reveal how finely tuned collective scattering can surpass conventional limits, advancing the control of wave localization in subwavelength structures.
