Multipolar-sensitive engineering of magnetic dipole spontaneous emission with a dielectric nanoresonator antenna
Abstract We propose an axisymmetric silicon nanoresonator with designed tapered angle well for the extraordinary enhancement of the decay rate of magnetic dipole (MD) emitters. Due to the resonant coupling of a MD emitter and the MD mode of the subwavelength resonator, the Purcell factor (PF) can ea...
