摘要

Dynamic responses of fiber optic ring resonator (FORR) under triangle wave, sawtooth wave and sine wave phase modulation techniques are analyzed. Theoretical analysis shows that the performance of the resonator is affected by the fiber length L, and when L=0.075 m, the normalized output curves can reveal the steady-state performance of the resonator, which will be used in integrated optical resonance gyro (IORG). When L=0.75 m, the normalized output curves exhibit oscillatory behavior, which becomes more serious with the further increasing of L. In addition, the normalized output curves with different modulation frequency and power transmission coefficient of fiber are also analyzed. Results show that the oscillatory behavior becomes more seriously when modulation frequency changes from 33.4 kHz to 3340 kHz, the peak value of which becomes bigger. In addition, with the increasing of the power transmission coefficient alpha, the resonance curves become acute which exhibit the favorable performance of the FORR exactly.
