摘　　要：提出了一种旋转参考系中的时域有限差分算法,方便对光子学器件中的Sagnac效应进行系统研究,并通过集群系统设计平台下的软件仿真,验证了在不同旋转系下Sagnac相移与距离的关系及在时域有限差分算法中的稳定性。实验结果表明该算法能够有效地建模Sagnac效应,并可用于各种具有复杂几何结构和材料性质的器件在旋转参照系下的性能评估。We propose a finite-difference time-domain algorithm in a rotating reference frame to facilitate systematic study of Sagnac effect in photonic devices. Through the design of software simulation on a cluster system platform, the relation between Sagnac phase shift and distance in different rotation systems and the stability of finite-difference time-domain algorithm are verified. The experimental results show that the algorithm is capable of modeling the Sagnac effect effectively, and can be used for various devices with complicated geometry and material properties in the rotating reference performance evaluation system.
