Fiber-optic resonators can be used as ideal mechanical probes and chemical sensors owing to their unique sensitivity to static and dynamic strain applied to the fiber as well as to optical absorption or refractive index changes in the surrounding medium when the evanescent or the internal light field is exposed. The intrinsic properties of high-finesse fiber cavities, either based on Bragg-grating structures or closed fiber rings, are discussed for quasi-static and dynamic strain sensing. Laser illumination and high precision laser frequency-locking techniques are considered for low-noise, fast and wide dynamic range active interrogation. Also, possible detection schemes for liquid sensing and spectroscopy using fiber resonators are illustrated using single-frequency tunable lasers or supercontinuum comb generators as light sources.

“…This optical decay can be measured in the time domain and is typically on the order of nanoseconds to microseconds. Cavity ring-down measurements can be used to characterize the reflectivity of highly reflective mirrors [1,2] or the absorption spectra of gases, films and liquids [3,4]. Accurate measurements of ring-down times therefore require fast detectors and data acquisition devices.…”

Several mathematical models exist in the literature to describe the properties of optical resonators. Here, coupled mode theory and coherent superposition theory are compared and their consistency is demonstrated as they are applied to phase-shift cavity ring-down measurements in optical (micro-)cavities. In the particular case of a whispering gallery mode in a microsphere cavity these models are applied to transmission measurements and backscattering measurements through the fiber taper that couples light into the microresonator. It is shown that both models produce identical relations when applied to these traveling wave cavities.
