Hiba Alhalaby, Haitham Zaraket, M. Principe
Abstract
Resonant dielectric subwavelength structures made of high-refractive-index materials are an emerging powerful platform with unique advantages compared to plasmonic based nanostructures. Owing to the low ohmic losses, to their ability to localize optical near-field at nanoscale, and exciting both electric and magnetic resonant modes, high-index dielectric materials are being used in various applications. Starting from the first principles, we aim at showing how resonant dielectric nanostructures can be efficiently used to enhance photoluminescence signal from an excited molecule, and we review the most recent results present in the Literature.
