- Abstract summary: We employ a dual optical frequency comb spectrometer to readout a microfabricated cavity optomechanical accelerometer.
With this approach, we have achieved a displacement sensitivity of 3 fm/Hz$1/2$, a measurement rate of 100 kHz, and a dynamic range of 3.9 $times$ 10$5$.

- Abstract: Cavity optomechanical sensors can offer exceptional sensitivity; however,
interrogating the cavity motion with high accuracy and dynamic range has proven
to be challenging. Here we employ a dual optical frequency comb spectrometer to
readout a microfabricated cavity optomechanical accelerometer, allowing for
rapid simultaneous measurements of the cavity's displacement, finesse, and
coupling at accelerations up to 24 g (236 m/s$^2$). With this approach, we have
achieved a displacement sensitivity of 3 fm/Hz$^{1/2}$, a measurement rate of
100 kHz, and a dynamic range of 3.9 $\times$ 10$^5$ which is the highest we are
aware of for a microfabricated cavity optomechanical sensor. In addition,
comparisons of our optomechanical sensor coupled directly to a commercial
reference accelerometer show agreement at the 0.5% level, a value which is
limited by the reference's reported uncertainty. Further, the methods described
herein are not limited to accelerometry but rather can be readily applied to
nearly any optomechanical sensor where the combination of high speed, dynamic
range, and sensitivity is expected to be enabling.
