Experimental Investigation of an Optical Resonator Gyroscope with a Mach–Zehnder Modulator and Its Sensitive Elements

Today, the task of developing microoptical gyroscopes is topical. Usually, tunable lasers with a built-in frequency stabilization system are used in such gyroscopes. They comparatively bulky, which hinders real miniaturization optical We propose new approach implemented by using Mach–Zehnder modulator passive ring resonator connected to one its arms. This makes it possible obtain mutual configuration and use laser optional. Two resonators made polarization-maintaining fiber, suitable for as sensitive elements gyroscope, were realized investigated. Their Q-factor equal 14.5 × 106 28.9 106. The maximum sensitivity proposed method when described 3.2 1.8 °/h, respectively. first experimental setup gyroscope implementing this has been manufactured analyzed. When measuring rotation speed quasi-harmonic signal span phase, measurement accuracy was approximately 11 0.4 °/s,
