Abstract

The viability of an all-optical fibre optical thermocoupler for remote sensing of ultra-high temperatures, independent of electronics, is explored. Simple packaging of regenerated fibre Bragg gratings (FBGs) within silica capillaries were shown to protect the fibre structure sufficiently to allow the temperature measurement of a furnace element to >1500 °C; a temperature at which the regenerated FBG, which was written in relatively soft boron-codoped germano silicate glass, was shown to decay rapidly.
