| Summary: | We develop a miniaturized electrostatically tunable
optomechanical oscillator, whose frequencies can be
electrostatically tuned by as much as 10%. By taking
advantage of the optical and the electrical spring, the
oscillator achieves a high tuning sensitivity without
resorting to mechanical tension. Particularly, the high-Q
optical cavity greatly enhances the system sensitivity,
making it extremely sensitive to the motional signal, which
is often overwhelmed by background noise. |
