Elliptical-Cladding Polarization-Maintaining Fiber

The elliptical-cladding polarization-maintaining fiber is a specially designed stress-type PM fiber, whose structural characteristics provide excellent polarization-maintaining performance. Compared with bow-tie PM fibers, the elliptical-cladding design offers lower process complexity and better geometrical uniformity. By optimising the axial uniformity of the fiber and adopting independently developed inner and outer coating materials, this fiber exhibits outstanding temperature stability and birefringence performance. It is widely used in fiber optic gyroscopes, current transformers, and other polarization-sensitive components.
