Observing the viscous relaxation process of silica optical fiber at ~1000 C using regenerated fiber bragg grating (2019)

Abstract A regenerated fiber Bragg grating (RFBG) in silica fiber was used to observe the viscous relaxation process of the host silica fiber at high temperatures of around 1000 C. Two factors, preannealing time and loaded tension, which a ect viscous relaxation, were observed. When an RFBG is stretched after a longer preannealing, the measured viscosity of the optical fiber was observed to reach equilibrium faster, which means that preannealing accelerates viscous relaxation. A similar acceleration phenomenon was also observed when a larger load was applied to stretch the optical fiber, although the acceleration e ect of loaded tension was not as strong as in the preannealing case. The results play an active role in establishing e ective optical-fiber devices for application in high-temperature environments.
