Abstract: (1507 Views)
In this paper, we have investigated the state evolution of an Optomechanical system in which the mechanical spring constant as well as the optomechanical coupling coefficient have been modulated. It has been shown that the presence of the modulation leads to the squeezing of the mechanical momentum while in the absence of this effect there is no mechanical squeezing. For this purpose, we first obtain the evolution of the quantum state of the system and then we calculate uncertainties in the position and momentum operators of the mechanical oscillator. We have shown that for certain amounts of mechanical modulation strength, the momentum operator of the mechanical oscillator is squeezed.
Keywords: Optomechanical systems, quantum state engineering of the mechanical oscillator, squeezed state generation.
