We explore possibilities to electrically control optical bistability by interfacing a two-level atomic system with an extended graphene sheet. Our theory incorporates the self-interaction of the optically-excited atom and its coupling to electromagnetic vacuum modes, both of which are sensitive to the actively-tunable interband transition threshold in graphene, thus enabling electrical tuning between bistable configurations. We show that bistability and hysteresis can manifest in average radiation power and resonance fluorescence spectrum of the atom, with the latter exhibiting a transition between a single Rayleigh peak and Mollow triplet by tuning the Fermi energy of the graphene sheet. The optically-driven atom-graphene system thus constitutes a platform for active control over driven quantum optical systems for explorations in coherent quantum control and atomic physics.
