摘要：
本文对微球谐振腔和双锥形光纤组成的慢光系统进行了理论上的分析和仿真。使用定向耦合定理对单个微球谐振腔的输入输出特性及在过耦合状态下的有效相移、透射率、有效延时和光速与耦合系数、距离的函数关系进行了理论推导和数学仿真，并对仿真结果进行了分析。对引入慢光后的慢光陀螺仪进行了理论分析和仿真优化，确定了微球谐振腔的半径、微球谐振腔与双锥形光纤之间的距离。通过理论研究和数学仿真，得出了微球谐振腔的传输特性，并且得到了微球谐振腔的延时数学表达式，通过对光纤陀螺仪灵敏度的理论分析和仿真，得出引入慢光可以提高干涉型光纤陀螺仪的测量精度。?

Abstract：
In this paper，a slow light system consisting of microsphere resonators and double tapered fiber has been analysied and simulated in theoretical. A directional coupler theorem was used to deduct the input-output characteristic, state phase shift, the transmission rate, delay, and the speed of light of a single microsphere cavity resonator in overcoupling and got a function of distance for the theoretical derivation and mathematical simulationin, and simulation results are analyzed. And the theoretical analysis and simulation optimization of gyroscope after introduction of slow light were carried out to determine the radius microsphere resonator and the distance between microsphere resonator and the tapered fiber. In this thesis, through theoretical study and mathematical simulation, the transmission characteristics of microsphere resonator and its delay time mathematical expressions has been obtained. Through the theoretical analysis and simulation of the sensitivity of fiber optic gyroscope, it was proved that the introduction of slow light can improve the accuracy of interferometric fiberoptic gyroscope measurement.
