Paper Abstract

Regeneration of long period gratings (LPGs) in hydrogen-loaded, boron-codoped germanosilicate fibre is studied. The regenerated LPGs survive temperatures exceeding T > 950 °C. High temperature stability and stable spectra of these gratings were studied under different annealing temperatures. Regeneration was faster at higher temperatures, and occurred within 75 minutes in the region of 850 °C to 950 °C. These regenerated LPGs also exhibit ultra-low strain sensitivity.
