Abstract Combining the quantum optical properties of single-photon emitters with strong near-field interactions available in nanophotonic and plasmonic systems is a powerful way creating manipulation metrological functionalities. The ability to actively dynamically modulate emitter-environment particular interest this regard. While thermal, mechanical modulation have been demonstrated, electrical has remained an outstanding challenge. Here we realize fast, all-electrical between nanolayer erbium graphene, by in-situ tuning Fermi energy graphene. We demonstrate >1000-fold increased decay rate for ~25% emitters, electrically these frequencies up 300 kHz – orders magnitude faster than emitter’s radiative (~100 Hz). This constitutes enabling platform integrated technologies, opening routes entanglement generation collective plasmon emission or photon controlled waveform.
