Precision Mass Sensing by Tunable Double Optomechanically Induced Transparency with Squeezed Field in a Coupled Optomechanical System

Abstract

We present a scheme for all-optical precision mass sensing with squeezed field in a system consisting of an optomechanical cavity coupled to a charged nanomechanical resonator (NAMR) in terms of tunable double optomechanically induced transparency (OMIT) . We demonstrate that the accreted mass landing on NAMR can be achieved by measuring the splitting of the two transparency windows of the double OMIT. Moreover, our work shows this scheme for the quantized fields can be robust against temperature and cavity decay in somehow. Specifically, the precision measurement is from the noise spectrum, for these reasons, our scheme may provide a new paradigm for precision measurement based on the noise in the optomechanical system.
