Abstract

Optomechanical systems provide a unique platform for observing quantum behavior of macro- scopic objects. However, efforts towards realizing nonlinear behavior at the single photon level have been inhibited by the small size of the radiation pressure interaction. Here we show that is possible to realize significant optomechanical nonlinearities at the few quanta level in a strongly driven two- mode optomechanical system. In particular, as the strength of the driving laser increases the energy of one of the optomechanical normal modes approaches zero and the associated harmonic oscillator length becomes large. This leads to an enhanced single photon optomechanical coupling, scaling with the sideband resolution of the mechanics. We show that this could be measured in two-photon correlations when the system is in the side-band resolved regime with relatively large single-photon optomechanical coupling. These conditions are within the reach of current devices.
