Abstract
A differential birefringent fiber frequency-modulated continuous-wave Sagnac gyroscope is described. Due to the nature of the differential interferometer structure, the gyroscope can automatically eliminate the unexpected nonreciprocal phase drift (including the frequency drift of the light source) and make the resolution double.
