低双折射旋转光纤LB650 | LB1060 | LB1300 | LB1300RC | PME1300-10Spun fiber：Rotating glass preform during fiber drawing process produces a waveguide with unique properties: all fiber non-uniformities are averaged along all possible directions, effectively cancelling out total fiber birefringence. With total (but not local) birefringence close to zero, we obtain a fiber that will hold circular polarization (even when bent or twisted). Unlike conventional PM fibers that can hold only linearly polarized light, or annealed fiber that requires special handling, this low-birefringence fiber preserves both linear and circular polarization and can relay it with minimum error over large distances. Highly-birefringent preforms with incorporated stress produce spun fibers that can withstand significant bending and twisting and hold polarization over large number of coils with reasonable accuracy (without costly annealing process). Polarization accuracy in this case depends on local (instant) birefringence that introduces a small constant error, independent of fiber length. Elliptical core fiber Our elliptical-core PME1300-10 fiber provides high polarization extinction and insensitivity to bending and twisting stress. Unlike conventional PM fibers, birefringence of the elliptical-core waveguide has low thermal dependence (10 times lower than Panda). Due to core geometry the splice losses to a conventional circular-core fiber (SMF, Panda or Bow-tie) are asymmetrical - 0.5 dB for circular-toelliptical coupling and 2.5 dB for elliptical-to-circular arrangement.Elliptical core fiber：Our elliptical-core PME1300-10 fiber provides high polarization extinction and insensitivity to bending and twisting stress.
