摘要
Nitrogen-doped silica-core fibre is discussed in the context of a technological basis for the fabrication of Bragg gratings for sensors with enhanced temperature resistance. To estimate applicability of this fibre type for high-temperature Bragg grating sensors manufacturing, the following features are analyzed: fibre preforms fabrication technology, fibre characteristics, and particularities of Bragg gratings writing in it. Practical application of this sensor type in thermometry is given as an example.
