1. A method of using an optical microresonator based RF oscillator as a sensor comprising the following steps:

  • generating optical power oscillations by coupling an optical energy source to said optical microresonator;

    establishing a stable oscillation frequency; and

    measuring the oscillation frequency variation induced by a substance to be measured as said substance interacts with said optical microresonator.
