Abstract
An optical sensor readout Interrogates an optical sensor and includes: a microcavity sensor that receives an optical frequency comb, produces a post-sensor optical frequency comb from the optical frequency comb based on a physical perturbation subjected to the microcavity sensor, and communicates the post-sensor optical frequency comb to a photo detector; an electro optic modulator in optical communication with the microcavity sensor and that receives input light and a radiofrequency drive signal, produces the optical frequency comb from the input light based on the radiofrequency drive signal, and communicates the optical frequency comb to the microcavity sensor; and the photo detector in optical communication with the microcavity sensor and that: receives the post-sensor optical frequency comb from the microcavity sensor; receives frequency shifted light; and produces a radiofrequency interferogram from interference between the post-sensor optical frequency comb and the frequency shifted light.
