Description
Summary:Abstract In this paper, the use of optical parametric amplifier to effectively improve the detection performance of nonlinear opto-mechanical system is studied theoretically. At the same time, it is found that by adjusting the nonlinear gain of the optical parametric amplifier and the effective detuning between the input light field and the cavity field, the quantum noise of about 14dB in the squeezed quadrature can be reduced, and the sensitivity of weak force detection can be increased by more than 2 times. On the other hand, the phenomenon of reaction noise cancellation caused by nonlinear cavity combined with homodyne measurement is analyzed and the method of quantum non-destructive measurement is realized, which provides technical reference for weak force detection of nonlinear opto-mechanical system.
