Transmission Spectrum and Four‑Wave Mixing in Three‑Cavity Hybrid Optomechanical System
The rapid development of cavity optomechanical systems has attracted extensive attention, and these systems are widely used in quantum information and precision measurement. In recent years, three-cavity optomechanical systems have attracted considerable attention. Compared with the single-mode optomechanical system, the multiple-mode system provides significantly higher flexible controllability. Furthermore, optomechanically induced transparency and four-wave mixing have been research hotspots in different optomechanical systems. For example, the four-wave mixing in a hybrid optomechanical system is theoretically investigated, which has important implications for the nonlinear optical properties. It is of great significance for theoretically exploring the transmission spectrum and four-wave mixing in a three-cavity optomechanical system.
The hybrid optomechanical system consists of a microwave cavity a with resonance frequency ω
When the optical cavity c2 is absent in the hybrid optomechanical system (J=0), the transmission spectrum of the probe field shows a Lorentzian line shape. However, when J≠0, the Lorentzian peak splits into two symmetrical peaks and a transparent window occurs (Fig.2). It is clear that with the increase in the coupling strength from J=0.5κo to J=2κo, the distance between the peaks increases, and the peak value of the transmission spectrum of the probe field also increases (Fig.3). We depict the variation of the four-wave mixing spectrum with the detuning of the probe field-cavity field
We investigate the optomechanically induced transparency and four-wave mixing in a hybrid optomechanical system composed of two optical cavities, a microwave cavity, and a mechanical resonator. When the microwave cavity is driven to the red sideband and the two optical cavities are driven to the blue sideband, the optomechanically induced transparency can be changed by changing the coupling strength between the two optical cavities. Furthermore, the four-wave mixing spectrum can be modulated by controlling the coupling strength between the two optical cavities and by changing the frequency of the mechanical resonator during resonant detuning
