Abstract

Recently, optical phenomena generated by interfering electric and magnetic modes through the use of high-index dielectric materials have garnered significant attention. Destructive interference of scattered fields produced using toroidal loops of electric or magnetic fields known as anapole modes is one such nontrivial effect. Here, we demonstrate the viability of ultrananocrystalline diamond for metasurface applications and the potential it offers for coupling anapole modes. Because such modes are confined within the disks, coupling between this mode and the absorption and emission modes of MoS₂ induces an enhancement in the photoluminescence. This highdensity, subwavelength light-matter interaction method serves as a platform toward mitigating the lossy effects inherent to traditional plasmonic materials while spatially confining the mode plasmonic modes in an effort to achieve more efficient methods of enhancing light-matter interactions.
