Abstract :
In this work, we evaluated the performance, at elevate temperatures, of fiber Bragg gratings recorded using high power UV lasers. The evolution of grating wavelengths and reflectivities when fibers were submitted to several thermal cycles was determined. The range of thermal stability of the gratings was found to be suitable for telecommunication and sensing applications.
