Stability Study of Photo-inscribed Bragg Gratings in Sapphire Fibers at Very High Temperature
Abstract
Fiber Bragg gratings inscribed by femtosecond laser in sapphire fibers were subjected to thermal cycling up to 1500°C. Adding a multimode silica fiber reduces modal interference, improves the quality of the Bragg spectrum and the measurement accuracy. The measurement uncertainty is about 1.9°C at 1500°C.
