Enhanced Purcell factor for nanoantennas supporting interfering resonances

We study the effect of coupled resonances and quasibound states in the continuum (quasi-BICs) on the Purcell factor in dielectric resonant nanoantennas. We analyze numerically interfering resonances in a nanodisk with and without a substrate when the modes are coupled to an emitter localized inside...
