Abstract

Nanoparticle on Mirror (NPoM) plasmonic cavity can be utilized to enhance the spontaneous decay rate of a quantum emitter to a great extent. Here, we calculated the Purcell factor of a quantum emitter placed in such a cavity using COMSOL Multiphysics software. We first simulated the extinction cross-section of a nanorod placed on top of a metal film separated by a small gap. Then, we calculated the Purcell factor of a quantum emitter for a varying gap. We observed that the Purcell factor is greatly enhanced when the gap between the nanorod and the metal film is sufficiently low (⪅4 nm).
