Laser-driven photonic-bandgap fiber optic gyroscope with negligible Kerr-induced drift.
We predict theoretically and confirm experimentally that the Kerr-induced phase drift of a fiber optic gyroscope (FOG) operated with a laser instead of a broadband source is virtually eliminated when the sensing coil is made of an air-core photonic-bandgap fiber. This is the first demonstration of a laser-driven FOG with a Kerr-induced drift low enough to meet the inertial navigation requirement for a 10-h transcontinental flight.
