Here we present an optomechanical inertial accelerometer with resonant frequency readout, where the transducer's core photonic crystal has been designed to provide linear input-output dependence, which is further enhanced by our integrated linearization model.

We further our work on precision optomechanical inertial sensing by designing an integrated frequency counter for RF readout of our inertial sensor. We implement signal conditioning and frequency-to-digital conversion, obtaining a sub-Hertz measurement resolution.
