Twisting and annealing optical fiber for current sensors [PDF]

Journal of Lightwave Technology, 1996
We demonstrate that twisting a fiber a few turns per meter before it is annealed largely eliminates the residual linear birefringence. This dramatically improves the yield of annealed coils used for current sensing and makes it possible to use fibers that previously had large residual linear birefringence.
