We report a Silicon nano-opto-mechanical device in which a nanomechanical doubly-clamped beam resonator is integrated to an optical microdisk cavity. Small flexural oscillations of the beam cause intensity modulations in the circulating optical field in the nearby microdisk cavity. By monitoring the corresponding fluctuations in the cavity transmission via a fiber-taper, one can detect these oscillations with a displacement sensitivity approaching 10 fm·Hz-1/2 at an input power level of 50 μW.

- The development of efficient motion transducers for nanoelectromechanical systems (NEMS) is crucial for both research and technological applications.
- A single-wire nanomechanical transducer interface using a fiber-optic cable and near-field optomechanical interactions was created to actuate individual NEMS resonances.
- The system demonstrated high sensitivity in detecting nanomechanical motion, measuring 63 NEMS resonators with a displacement sensitivity ranging from 2-8 pm·Hz(-1/2) at low power levels.
We describe a simple approach to detect small mechanical displacements by scattering evanescent optical waves confined around an optical waveguide. Our experimental setup consists of a microcantilever brought into the proximity of a tapered optical fiber. The scattering of evanescent waves and hence the optical transmission through the tapered fiber is strongly dependent on the separation between the fiber and the microcantilever, allowing for sensitive detection of the small oscillations of the microcantilever.
