An optical resonator is modified by changing the optical path length of the resonant cavity to enhance the sensitivity of the device. The resonator-based sensors provide an attractive alternative for existing chemical sensors using a change of refractive index inside a sensitive region to detect the species in question, by promising high resolution at low cost.
