Cavity optomechanical systems are being widely developed for precision force and displacement measurements. For nanomechanical transducers, there is usually a trade-off between the frequency (fM) and quality factor (QM), which limits temporal resolution and sensitivity. Here, we present a monolithic cavity optomechanical transducer supporting both high fM and high QM. By replacing the common doubly clamped, Si3N4 nanobeam with a tuning fork geometry, we demonstrate devices with the fundamental…

Frequency Stabilization of Nanomechanical Resonators Using Thermally Invariant Strain Engineering.

Temperature- and residual stress-insensitive 16.51 MHz tuning fork nanobeam resonators with nonlinear clamps defining the stress and frequency by design are experimentally demonstrated, achieving low fractional frequency sensitivity on par with state-of-the-art driven devices of similar mass.

Clamp-Tapering Increases the Quality Factor of Stressed Nanobeams.

It is found that tapering the beam near the clamps, thus locally increasing the stress, leads to an increased Q of MHz-frequency low order modes due to enhanced dissipation dilution.
