Paper 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.
