Paper Abstract
In this paper, the thermal degradation mechanism of ultraviolet-induced fiber Bragg gratings (FBGs) written in silica
fiber doped with germanium has been developed. The thermal degradation up to 840 oC has been repeatedly examined,
and their reflectivity and Bragg wavelength change have been carefully observed. In addition, the temperature
characteristic of the FBG is tested by putting it into a silica tube furnace heated from room temperature to 600 oC. The
experiment results obtained has shown that the FBGs' thermal behavior is similar to a spring's. Therefore, a novel
viewpoint, atomic elastic model applied to explain the thermal degradation mechanism of FBGs, is firstly present. The
work is closely related to the use of FBGs for application in temperature sensor field, and the work is also related to
form mechanism of FBGs.
