Mechanical oscillations frozen on discrete levels by two optical driving fields
(American Physical Society, 2020-07-20)
We report a synchronization phenomenon which is simulated with an optomechanical system driven by two equally strong fields with different frequencies. Once the frequencies of the driving fields are properly matched, the ...
Ultra-high optical nonreciprocity with a coupled triple-resonator structure
(IOP Publishing Ltd., 2021)
Optical transmission nonreciprocity as a widely investigated phenomenon is essential to various applications. Many sophisticated mechanisms have been proposed and tested for achieving the optical nonreciprocity on integrated ...
Breaking the optomechanical cooling limit by two drive fields on a membrane-in-the-middle system
(AMER PHYSICAL SOC, 2019)
We present a theoretical scheme for ground-state cooling of a mechanical resonator in a membrane-in-themiddle optomechanical system (OMS) driven by two red-detuned drive fields. The details of dynamical evolution of OMS ...
Highly efficient cooling of mechanical resonator with square pulse drives
(OPTICAL SOC AMER, 2018)
Ground state cooling of mechanical resonator is a way to generate macroscopic quantum states. Here we present a study of optomechanical cooling under the drive of square pulses without smooth profile. By illustrating the ...
Entangling Two Macroscopic Mechanical Resonators at High Temperature
(AMER PHYSICAL SOC, 2020)
At high temperature, thermal decoherence dominates so that the entanglement of quantum states is difficult to preserve. Realizing high-temperature entanglement is, therefore, a challenge to the current quantum technologies. ...
Efficient ground state cooling of a membrane by the combination of continuous-wave field and pulses
(IOP Publishing Ltd, 2021-05-28)
We present an approach that realizes the ground state cooling of the membrane-in-middle optomechanical system. Instead of straightforwardly using the continuous-wave (CW) or pulsed external drives, we consider the combinations ...
Nonlinear optomechanical resonance entering a self-organized energy transfer pattern
(Chaos, Solitons and Fractals, 2023-08)
The energy transfer between different subsystems or different vibration modes is always one of the most interested problems in the study of the resonance phenomena in coupled nonlinear dynamical systems. With an optomechanical ...
