title = "Earth's rotation rate detection using an extremely-large semiconductor fiber optic gyroscope extending over 10,000 m2",
abstract = "We detect the Earth's rotation rate using a semiconductor fiber optic gyroscope (S-FOG), which is an active ring laser gyroscope that consists of a semiconductor optical amplifier (SOA) and a fiber optic ring resonator. Four different optical fiber layouts with different scale factors in rotation rate measurement are configured and measured. Expected Sagnac beat signals proportional to the scale factors are observed. The maximum layout of S-FOG is extended over 10,898 m2, which, to our knowledge, is the largest active ring laser gyroscope ever built.",
