Abstract

The work demonstrates for the first time a thermal regenerated grating (RG) operating at an ultra-high temperature up to 1400 degrees C. A new class of photosensitive optical fiber based on erbium-doped yttrium stabilized zirconiacalcium-alumina-phospho silica (Er-YZCAPS) glass is fabricated using modified chemical vapor deposition (MCVD) process, followed by solution doping technique and conventional fiber drawing. A type-I seed grating inscribed in this fiber is thermal regenerated based on the conventional thermal annealing technique. The investigation result indicates that the produced RG has an ultrahigh temperature sustainability up to 1400 degrees C. The measured temperature sensitivities are 14.1 and 15.1 pm/degrees C for the temperature ranges of 25 degrees C-1000 degrees C and 1000 degrees C-1400 degrees C, respectively.
