Abstract :
An Mach-Zehnder (M-Z) interferometer coupled with the nested fiber ring resonator is theoretically demonstrated. The results show that the dispersion sensitivity of the interferometer is significantly enhanced by the strong dispersive response of the resonator. The sensitivity of the temperature sensor based on the nested fiber ring resonator coupled M-Z interferometer can achieve 320rad/°C, about ten times of that in traditional M-Z interferometer.
