Engineering Optical and Mirror Bi-stability Mechanically

Abstract

We demonstrate the occurrence of bistable behavior, both in terms of optics and mirror movement, within an externally modulated nano-transducer system. This setup comprises a Fabry-Perot cav ity driven by apowerfullaserandaweakerprobe,generatingopto mechanicalcoupling. Anelectro-mechanicalsystemintroducesCoulomb coupling, introducing non-linearity that induces optical bistability in the averageintracavity photon count, aswellasmirrorbistability in the steady mechanical motion of the mirrors.
