It is found that the Kerr effect, as the major error source of the rotation rate measurement in this gyroscope, causes a bias of beat frequency with nonlinear dependence on rotation rate. A differential Stokes power of 1 mW inside the ring resonator is measured to produce a beat frequency bias of 69 Hz, which agrees well with the theoretical expectationfibre optic sensorsgyroscopesoptical Kerr effectoptical resonatorsring lasersstimulated Brillouin scatteringtext::journal::journal article::research article
