| Abstract: | The theoretical and experimental study of the polarization maintaining (PM) ring resonator and its fiber directional couplers in the resonant fiber gyroscope are reported. The analytic equations of resonant conditions are deduced and the contribution of the resonator's basic parameters to the resonant performance is also analyzed. By modulating the fiber ring resonator using piezoelectric element, the resonant output is recorded. And the resonant characteristics of the PM ring resonator are obtained. At last the experimental results and a testing curve are given. And several problems to be solved in the resonant system are also proposed, which build the theoretical and experimental base of the study in the next stage. |
