“…The effective nonlinear coupling between the optical and mechanical modes in a quadratically coupled optomechanical system can be enhanced by a strong driving optical field as shown in Refs. [54,56,57,59]. Different from the previous studies [54,56], we find that there is an optimal value of the effec-tive nonlinear coupling strength for photon blockade before reaching the strong nonlinear coupling regime, and both photon and phonon blockades can be observed in a quadratically coupled optomechanical system with the same parameters.…”

We study photon, phonon statistics and the cross-correlation between photons and phonons in a quadratically coupled optomechanical system. Photon blockade, phonon blockade, and strong anticorrelation between photons and phonons can be observed in the same parameter regime with the effective nonlinear coupling between the optical and mechanical modes, enhanced by a strong optical driving field. Interestingly, an optimal value of the effective nonlinear coupling strength for the photon blockade is not within the strong nonlinear coupling regime. This abnormal phenomenon results from the destructive interference between different paths for twophoton excitation in the optical mode with a moderate effective nonlinear coupling strength. Furthermore, we show that phonon (photon) pairs or correlated photons and phonons can be generated in the strong nonlinear coupling regime with a proper detuning between the weak mechanical driving field and mechanical mode. Our results open up a way to generate anticorrelated and correlated photons and phonons, which may have important applications in quantum information processing. |0, > |4 0 > J 2 J 2 2 J 6 J 6 2 Non-coupling basis J 3 2 J 2 Diagonal basis |1 0 > J 4 J 4

“…With the rapid development of microfabrication technology, cavity optomechanical system [1][2][3][4] is becoming an appealing candidate to connect a broad spectrum of photonic, electronic, and atomic devices, besides being studied for fundamental questions of macroscopic systems in the quantum limit [5]. Recently, enormous progresses have been achieved that aim at the applications of optomechanical systems in ultra-high precision measurement [6][7][8][9][10][11][12], quantum information processing [13], quantum illumination [14] to optomechanically induced transparency [15][16][17][18][19][20][21], absorption [22,23], and amplification [24][25][26][27][28].…”

We study the directional amplification of an optical probe field in a three-mode optomechanical system, where the mechanical resonator interacts with two linearly-coupled optical cavities and the cavities are driven by strong optical pump fields. The optical probe field is injected into one of the cavity modes, and at the same time, the mechanical resonator is subject to a mechanical drive with the driving frequency equal to the frequency difference between the optical probe and pump fields. We show that the transmission of the probe field can be amplified in one direction and deamplified in the opposite direction. This directional amplification or de-amplification results from the constructive or destruction interference between different transmission paths in this three-mode optomechanical system.

“…Together with the sinusoidal modulation of the optomechanical coupling, the resonant nonlinear photon-phonon interaction could be enhanced to the single-photon strong-coupling regime by mechanical parametric amplification. Note that the mechanical parametric amplification could also be used to boost mechanical signals in micro-and nanoelectromechanical systems [42,43], to squeeze the mechanical oscillator beyond the 3dB limit [44], to enhance the photon-photon interaction in a two mode OMS [45], to yield optical amplification and squeezing [46], and to achieve optical nonreciprocity [47,48].…”

The nonlinear quantum regime is crucial for implementing interesting quantum effects, which have wide applications in modern quantum science. Here we propose an effective method to reach the nonlinear quantum regime in a modulated optomechanical system (OMS), which is originally in the weak-coupling regime. The mechanical spring constant and optomechanical interaction are modulated periodically. This leads to the result that the resonant optomechanical interaction can be effectively enhanced into the single-photon strong-coupling regime by the modulation-induced mechanical parametric amplification. Moreover, the amplified phonon noise can be suppressed completely by introducing a squeezed vacuum reservoir, which ultimately leads to the realization of photon blockade in a weakly coupled OMS. The reached nonlinear quantum regime also allows us to engineer the nonclassical states (e.g., Schrödinger cat states) of cavity field, which are robust against the phonon noise. This work offers an alternative approach to enhance the quantum nonlinearity of an OMS, which should expand the applications of cavity optomechanics in the quantum realm.
