Demonstration of enhanced Allan Variance in optical gyroscope using squeezing techniques, indicating potential for improved precision.
With a 1km Sagnac fiber interferometer and a 7.5dB fiber based squeezing source, we reported the first demonstration of squeezing enhanced fiber optical gyroscope with 2.6dB of enhancement of Allan Variance beyond the shot noise.
