Abstract

Fluoride-based fibres have attracted notable attention for their thermal properties, such as a thermal expansion coefficient that is 30 times larger than that of silica fibres. In this work, we discuss the thermal behaviour of FBGs inscribed in different fluoride-based fibres, such as ZBLAN and InF3, for application as thermal sensors for cryogenic temperatures. The FBGs were inscribed utilizing the Talbot interferometer with a Ti:Sapphire fs-laser combined with frequency-doubling crystal.
