Abstract : This patent discloses a fiber optic gyroscope comprising a Sagnac interferometer including a (3 X 3) optical directional coupler. The gyroscope is driven with an essentially unpolarized broadband spatially coherent light beam supplied by a super-luminescent diode source. A significant reduction in baseband noise occurs due to the use of the essentially unpolarized light beam.
