Effects of high temperature and pressure on silica optical fibres and the implications on optical fibre sensors
Effects of high temperature and pressure on silica optical fibres and the implications on optical fibre sensors
We report on the observed effects of liquids at high temperature and pressure on silica optical fibres, sensors and gratings. We propose that the diffusion of molecules into the silica and the resultant expansion of the network are responsible for observed fibre expansions of up to 0.2% and Bragg wavelength increases of 2nm at 1525nm. A developmental solution in the form of amorphous carbon hermetic coatings has shown a reduction of these effects by an order of magnitude at 300°C.

Abstract
We report on the observed effects of liquids at high temperature and pressure on silica optical fibres, sensors and gratings. We propose that the diffusion of molecules into the silica and the resultant expansion of the network are responsible for observed fibre expansions of up to 0.2% and Bragg wavelength increases of 2nm at 1525nm. A developmental solution in the form of amorphous carbon hermetic coatings has shown a reduction of these effects by an order of magnitude at 300°C.
