Patent abstract
A method and system are disclosed for detecting the presence of a perturbation of a microresonator including the step of 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. The method further includes 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. Another step of the method is comparing the first frequency shift and the second frequency shift.
