Abstract :
We propose an add-drop fiber ring resonator (AFRR) coupled Mach-Zehnder (M-Z) interferometer for highly sensitive sensing. Theoretically it is shown that the sensitivity of such an interferometer can be much higher than that of a single fiber ring resonator (SFRR) coupled M-Z interferometer as a result of the dispersion properties of the add-drop ring resonator. The sensitivity of our configuration can achieve 49.5, which is enhanced by 30.06 compared to that of the SFRR coupled M-Z interferometer. This proposed configuration enables highly sensitive, compact and stable sensors.
