Abstract

Based on insights from a new model of scattering in FOGs for high-coherence sources, we demonstrate experimentally that a fiber optic gyroscope (FOG) can be driven with a laser of suitable linewidth and exhibit short and long-term performance matching that of a FOG driven by a broadband source. This innovation can be combined with the use of hollow-core fiber in the sensor coil to produce new FOGs exceeding current standards.
