Abstract

We demonstrate a striping-inscribing-recoating (SIR) method to fabricate kilometer-long backscattering-enhanced fiber for distributed sensing. Addressing the challenge of continuous low-loss stripping enables controllable grating inscription and flexible recoating for sensing in harsh environments.
