“…Detection of absolute rotation has significant importance in fundamental physics for testing gravitation theories [1,2] and in practical applications for improving navigation systems [3]. The Sagnac effect [4] is one of the most prominent methods [5][6][7][8][9] for detection of absolute rotation.…”

We propose a method to avoid the mode-locking problem in an ring laser gyroscope by restricting the lasing field inside the gyroscope to one direction only. Output from this unidirectional gyroscope is split into a reference field and a signal field, which is sent into a dispersive system so that it acquires an additional phase when its frequency changes because of the Sagnac effect. Angular velocity of absolute rotation is estimated by measuring the phase of the signal field. Noise properties of the dispersive system, created by using optomechanically induced transparency, are studied and the conditions for optimal performance of the gyroscope are derived.

“…Detection of absolute rotation [1,2] has significant importance in fundamental physics for testing gravitation theories [3,4] and in practical applications for improving navigation systems [5,6]. The Sagnac effect [7][8][9][10][11] and detection of rotation induced pseudo forces [12,13] are the two most commonly used methods for absolute rotation detection.…”

We propose an application of two-dimensional optomechanical oscillator as a gyroscope by detecting the Coriolis force which is modulated at the natural frequency of the optomechanical oscillator. Dependence of gyroscopeʼs sensitivity on shot noise, back-action noise, thermal noise, and input laser power is studied. At optimal input laser power, the gyroscopeʼs sensitivity can be improved by increasing the mass or by decreasing the temperature and decay rate of the mechanical oscillator. When the mechanical oscillatorʼs thermal occupation number, n th , is zero, sensitivity improves with decrease in frequency of the mechanical oscillator. For  n 1 th , the sensitivity is independent of the mechanical oscillatorʼs frequency.

“…1,2 After avoiding the lock-in effect, [3][4][5][6] the interest in the conceptual design of the laser gyro began to focus on the practical solution of stabilizing the beam path. [7][8][9][10][11] Additionally, control scheme and experimental behavior analysis of piezoelectricactuator can be considered to apply and operate the piezoelectricactuator properly. 12,13 This paper presents a practical mathematical model of a piezoelectric actuator used in the laser gyros.…”
