Lire la suite >Cavity optomechanics provides a method for using laser photons to manipulate/detect mechanical objects inside optical cavities in the quantum regime [1]. It is attractive for applications in quantum information processing and ultra-sensitive detection. Inspired by the achievements of cavity optomechanics and circuit quantum electrodynamics (QED), researchers start to develop microwave optomechanical platforms by using microwave photons and superconducting resonators. These systems exhibit inherently many physical aspects from optics and exhibit desirable flexibilities in design and integration with nowadays’ quantum engineering architecture. Up to now, both input-output theory and Hamiltonian deduced from quantum optics are widely employed in microwave optomechanical systems. Here, we present the classical circuit model based on a lumped element LCR microwave circuit which has been widely used in microwave optomechanical experiment design [2]. Based on this model, we deduce analytical expressions to describe interactions between microwave signals and mechanical motions and also the thermal fluctuation spectrum of the mechanical oscillator as the output of the microwave cavity. In addition, we make a comparison between our classical LCR circuit model and the cavity optomechanical model derived from quantum optics and discuss critical parameters in the designing microwave optomechanical devices.[1] M.
