摘要
An interferometer employed, in part, as a Sagnac interferometer or fiber optic gyro (FOG) includes a light source that provides a source light wave that is split into first and second light waves that are directed to traverse a defined optical loop path in opposite directions. The defined optical loop path in accordance with the present invention is provided by multiple waveguides wound into a coil such that the opposite traveling first and second light waves serially travel through all of the waveguides in opposite directions around the optical loop path.
