1. A method of detecting the presence of a perturbation of a microresonator comprising:

  • exciting at least first and second resonant guided optical modes of a microresonator with a light source that is in optical communication with the microresonator;

    inducing a first frequency shift in the first resonant guided optical mode and a second frequency shift in the second resonant guided optical mode, wherein the second frequency shift can be zero; and

    comparing the first frequency shift and the second frequency shift.
