Abstract

We demonstrate integrated nano-optomechanical systems with driven flexural resonance up to 760 MHz in the ultrahigh frequency band. The mechanical element of the device is embedded in a slot waveguide racetrack optical resonator with an optical quality factor of 60 000. Displacement sensitivity of 0.45× 10-15 m/ Hz at 127 MHz is achieved in this circuit cavity configuration.
