Sagnac interferometer having the nearly zero temperature sensitivity made by different birefringent optical fibers

摘要

The Sanac interferometer with offset temperature sensitivity using heterogeneous birefringent optical fibers according to a preferred embodiment of the present invention comprises: a first optical fiber, and a first optical fiber that is bonded to the first optical fiber such that at least one optical axis is perpendicular to the optical axis of the first optical fiber. It includes 2 optical fibers, and each length of the first optical fiber and the second Guam Seongyu is set to offset temperature sensitivity.
