Fabry-Perot effect on dimer nanoantennas

► We investigate the interaction between a single quantum emitter and dimer nanoantennas through a Fabry-Perot structure composed of an appropriate combination of two dielectric layers. ► Numerical calculations show that the directivity and excitation rate of a single dimer is highly increased, and that multiple dimers arranged in an array configuration can be enhanced due to the wide aperture field generated by a single emitter.
