High-precision optical fiber sensing beyond 1000{\deg}C

Optics 2024-08-07 v1 Applied Physics

Abstract

Sapphire fiber can withstand around 2000{\deg}C, but it is multimoded, giving poor precision sensors. We demonstrate a single-mode sapphire fiber Bragg grating temperature sensor operating up to 1200{\deg}C. The repeatability above 1000{\deg}C is within {\pm}0.08%.
