Abstract

Photonic cavities are valued in current research owing to the multitude of linear and nonlinear effects arising from densely confined light. Cavity designs consisting of low loss dielectric materials can achieve significant light confinement. Until now, the basic concepts in all-dielectric photonics such as anapole resonances have been primarily studied in high index materials. Here, we use photonic simulation to propose fabricable designs for higher confinement in low index dielectric cavities by incorporating the extensively studied isolated dielectric nanodisk into broader host structures. We further discuss on hexagonal boron nitride nanodisks for their potential use in quantum and nanop..
