This paper reports the results from two experimental closed loop gyroscopes using ordinary single mode fiber. Rotation rate bias stability data are presented for both short term (T = 1 sec) and long term (T = 100 sec., NT = 6 hrs). The performance of our systems is displayed in the frequency domain as well as in the time domain. The best performance achieved was a rotation rate noise of .9 °/hr for 1 sec. integration, .30 °/hr for 10 sec. integration and in the long term .08 °/hr for 100 second integration. The extrapolated drift, .2 ° / âœ"hr, was less than an order of magnitude above the shot noise limit. Our second (breadboard) gyroscope has achieved a long term (6 hours) bias stability of 1 °/hr.
