Sensors using optical RF oscillators

摘要

An optical microresonator based RF oscillator sensor for measuring mass, temperature, and particle/molecule concentration. An optical energy source is coupled to the optical microresonator to generate optical power oscillations at Rf frequencies. A stable or reference RF oscillation frequency is established which allows for measuring oscillation frequency variations induced by the interaction of the substance with the optical microresonator.
