Abstract :
In this paper, the linear quadratic Gaussian (LQG) control method is used to tackle the problem of mode-squeezing in optomechanical sensors. Coherent-feedback quantum control is synthesized by incorporating both shot noise and back-action noise to attenuate the output noise well below the shot noise level. The effectiveness of the proposed control strategy in squeezing the cavity output beam is demonstrated by simulation.
