With an increasing coupling between light and mechanics, nonlinearities beginto play an important role in optomechanics. We solve the quantum dynamics of anoptomechanical system in the multi-photon strong coupling regime retainingnonlinear terms. This is achieved by performing a Schrieffer-Wolfftransformation on the Hamiltonian including driving terms. The approach isvalid away from the red- and blue-sideband drive. We show that the mechanicalresonator displays self-sustained oscillations in regimes where the linearizedmodel predicts instabilities, and that the amplitude of these oscillations islimited by the nonlinear terms. Related oscillations of the photon number arepresent due to frequency mixing of the shifted mechanical and cavityfrequencies. This leads to additional peaks in the cavity's power spectraldensity. Furthermore, we show that it is possible to create phonon states withsub-Poissonian statistics when the system is red-detuned. This result is valideven with strong driving and with initial coherent states.
