Abstract :
Summary form only given. We show the enhanced thermal stability and excellent reliability of grating sensors written in tin-doped silica fibers (SS) up to a temperature of approximately 800/spl deg/C. At this temperature all the other gratings have been completely erased. Due to the improved stability above 500/spl deg/C and excellent repeatability, SS fiber is the best choice for high temperature thermometers or fiber Bragg sensors.
