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.
