“…In our scheme, this is achieved by placing an array of membranes in the middle of an optical cavity so that the interaction between the optical and mechanical mode is proportional to the square of the displacement. By making use of the adiabatic approximation, we can treat the optical field as a controllable reservoir [37,38], which is quite different from the biological systems where the two-phonon processes are determined by the environment. Analytical and numerical methods show that the critical optomechanical coupling strength required to achieve the Fröhlich condensate scales as N 3 (N is the number of membranes).…”

We propose that the optomechanical systems can be potential platforms to implement the Fröhlich condensate of phonons. We consider a one-dimensional array of membranes coupled to the cavity field via a quadratic interaction, and the cavity is pumped by an external laser. Analytical and numerical results predict that the high phonon occupancy of the lowest or highest mechanical mode is achievable depending on the detuning of the driving laser, the optomechnical strength, and the temperature. The decoherence of the Fröhlich condensate can be largely suppressed by the large number of membranes. Our results shed light on narrow-linewidth phonon laser, energy conversion/transfer, and efficient multimode cooling.

“…Many efforts have been invested in the single-photon strong-coupling regime of linear optomechanics both theoretically [26][27][28][29][30][31][32][33][34][35][36] and experimentally [37][38][39][40]. In recent years, much attention has been paid to the study of quadratic optomechanical systems [41][42][43][44][45][46][47][48][49][50][51][52][53]. A few methods have been suggested to enhance the quadratic coupling strength of optomechanical systems [54][55][56].…”

Enhancing quadratic optomechanical coupling via a nonlinear medium and lasers

We propose a scheme to significantly increase quadratic optomechanical couplings of optomechanical systems with the help of a nonlinear medium and two driving lasers. The nonlinear medium is driven by one laser and the optical cavity mode is driven by a strong laser. We derive an effective Hamiltonian using squeezing transformation and rotating wave approximation. The effective quadratic optomechanical coupling strength can be larger than the decay rate of the cavity mode by adjusting the two optical driving fields. The thermal noise of squeezed cavity mode can be suppressed totally with the help of a squeezed vacuum field. Then, a driving field is applied to the mechanical mode. We investigate the equal-time second-order correlations and find there are photon, phonon, and photon-phonon blockades even when the original single-photon quadratic coupling is much smaller than the decay rate of the optical mode. In addition, the sub-Poissonian window of the two-time second-order correlations can be controlled by the mechanical driving field. Finally, we show the squeezing and entanglement of the model could be tuned by the driving fields of the nonlinear medium and mechanical mode.

“…In practical, most optomechanical systems naturally support the multimodes [4,[38][39][40], and these modes can be excited by polychromatic laser drive [41]. With the advantages of multiple degrees in multimode optomechanical systems [42], dissipation engineering [43] holds huge potential in all-optical information processing [32,44,45], where two or more mechanical or optical modes lead to a wealth of different possible schemes.…”

We propose an optomechanical dissipation engineering scheme by introducing an ancillary mechanical mode with a large decay rate to control the density of states of the optical mode. The effective linewidth of the optical mode can be reduced or broadened, manifesting the dissipation engineering. To prove the ability of our scheme in improving the performances of the optomechanical system, we studied optomechanical entanglement and phonon cooling. It is demonstrated that the optomechanical entanglement overwhelmed by thermal phonon excitations could be restored via dissipation engineering. For the phonon cooling, an order of magnitude improvement could be achieved. Our scheme can be generalized to other systems with multiple bosonic modes, which is experimentally feasible with advances in materials and nanofabrication, including optical Fabry-Perot cavities, superconducting circuits, and nanobeam photonic crystals.
