We study the optical bistability of an optomechanical system in which the position of a mechanical oscillator modulates the cavity frequency. The steady-state mean-field equation of the optical mode is identical to the one for a Kerr medium, and thus we expect it to have the same characteristic behavior with a lower, a middle, and an upper branch. However, the presence of position fluctuations of the mechanical resonator leads to a new feature: the upper branch will become unstable at…

Nonreciprocity in a strongly coupled three-mode optomechanical circulatory system.

This work derives a quantum Langevin equation (QLE) for the strongly coupled OMCS by suitably choosing the laser field, and gives a condition for the frequency of the laser and the mechanical decay rate, beyond which the optomechanical system has a unidirectional transmission regardless of how strong the optomerchanical coupling is.

Controllable optical bistability in a hybrid optomechanical system

We investigate, theoretically, the effect of optical feedback from a cavity containing an ultracold two-level atomic ensemble, on the bistable behavior shown by a mean intracavity optical field in an

Electro-optomechanical switch via tunable bistability and four-wave mixing

We investigate the tunable bistable behavior of a hybrid nano-electro-optomechanical system (NEOMS) composed of S-shaped in the presence of two-level atoms, trapped inside a Fabry–Pérot cavity, and

Normal-mode splitting and output-field squeezing in a Kerr-down conversion optomechanical system

An investigation is reported of the effects of a Kerr-down conversion nonlinear crystal inside an intrinsically nonlinear optomechanical cavity on the dynamics of the oscillating mirror, the

Laser Theory for Optomechanics: Limit Cycles in the Quantum Regime

Optomechanical systems can exhibit self-sustained limit cycles where the quantum state of the mechanical resonator possesses nonclassical characteristics such as a strongly negative Wigner density,

Controllable Bistability and Normal Mode Splitting in an Optomechanical System Assisted by an Atomic Ensemble

We consider a system consisting of a standard optomechanical cavity and a trapped atomic ensemble. In such a system, we mainly focus on the features of optomechanical bistability and normal mode

Steady-state mechanical squeezing and ground-state cooling of a Duffing anharmonic oscillator in an optomechanical cavity assisted by a nonlinear medium

In this paper, we study theoretically a hybrid optomechanical system consisting of a degenerate optical parametric amplifier inside a driven optical cavity with a moving end mirror which is modeled

Quantum simulation of tunable and ultrastrong mixed-optomechanics.

It is shown that the mixed-optomechanical interactions can enter the single-photon strong-coupling and even ultrastrong-Coupling regimes and the thermal noise of the driven mode can be suppressed totally by introducing a proper squeezed vacuum bath.
