Combining the advantages of photonics (low loss) and plasmonics (high field confinement), while mitigating their respective drawbacks, can greatly enhance the light-matter interaction efficiency. Here we make use of a time-dependent coupled mode theory in order to theoretically model the excitation of a plasmonic nanoantenna via a photonic resonator. We show that including the light source-nanoantenna direct coupling substantially enhances the overall coupling efficiency, maintaining the same input power.
