Abstract
Dynamic control of the optical bistability of a nonlinear nanoresonator is shown to be achievable by modifying the resonance of the optical cavity with a dielectric near-field tip. It is experimentally demonstrated that the operating regime of the nanocavity can be switched between monostable and bistable regimes. Finally, an analytical model is proposed which provides an adequate description of the properties of the whole nonlinear optomechanical system.
