侧耦合间隔谐振器序列（SCSSOR）显示出比传统波导大得多的幅度的强色散。我们研究了SCSSOR结构中的Sagnac效应。推导并讨论了该结构的Sagnac相位差的显式表达式。结果表明，灵敏度与谐振腔的数量和色散强度成正比。与其他谐振器结构相比，一个优点是不必保持每个谐振器的相同周长，这在实践中很难实现。结果还预测了SCSSOR结构可以用于实现高灵敏度和紧凑的集成旋转传感器和陀螺仪。
A side-coupled spaced sequence of resonators (SCSSOR) displays strong dispersion with a magnitude much larger than that of conventional waveguides. We investigate the Sagnac effect in a SCSSOR structure. An explicit expression of the Sagnac phase difference of the structure is derived and discussed. The results show the sensitivity is proportional to the number and dispersion intensity of resonators. Compared with other resonator structures, one advantage is that it is not necessary to preserve the same circumference of each resonator, which is difficult to realize in practice. The results also predict a SCSSOR structure can be used for the realization of highly sensitive and compact integrated rotation sensors and gyroscopes.
