A fiber gyroscope usin a polarization-maintaining optical fiber(PMF) has been studied. A phase shift of the laser beam passing through the PMF by an ultrasonic wave has been observed In this paper, the fiber gyroscope using the PMF and a polarization-maintaining fiber coupler(PMC) is presented. Moreover, the Sagnac phase modulation by the ultrasonic wave is studied.
