Abstract

We report a fiber-optic passive ring-resonator gyroscope that uses an external-cavity laser diode. The external-cavity laser diode is useful as the light source for the gyroscope if an appropriate cavity length is chosen. A rotation detection sensitivity of 10⁻² rad/sec was obtained with an integration time of 10 sec.
