Patent ID: 10416003

Abstract:
A resonating measurement system having at least a microelectromechanical system (MEMS) and/or nanoelectromechanical system (NEMS) is provided, including an optomechanical device comprising at least one resonating element at at least one resonance frequency of fr, and at least one optical element having an optical index sensitive to displacement of the at least one resonating elementl; excitation circuitry configured to excite the at least one resonating element at at least at one operating frequency of fm; an injection device configured to inject a light beam, having an intensity modulated at frequency of f1=fm+Δf, in the optomechanical device; and a photodetection device configured to measure an intensity of a light beam transmitted from the optomechanical device, the intensity having at least one component at frequency of Δf.
