Abstract
A method and system for transmitting source light to a plurality of Sagnac interferometers includes a first directional coupler that splits the source light into a second light beam and a third light beam. The second light beam supplies light to a first Sagnac interferometer and the second light beam supplies light to a second directional coupler, and the first directional coupler also delivers light returning from the first Sagnac interferometer to a first detector that is used to indicate rotation of the first Sagnac interferometer. The second directional coupler splits the third light beam into a fourth light beam and a fifth light beam, and the fourth light beam supplies light to a second Sagnac interferometer. The second directional coupler delivers light returning from the second Sagnac interferometer to a second detector, and the second detector provides a signal indicative of rotation of the second Sagnac interferometer.
