Material optimisation for high-temperature grating devices written by KrF excimer lasers.

We have studied the thermal stability of gratings written in fibres of different composition using a 248 nm KrF excimer laser. Measurements up to ~800 °C confirm the long-term thermal stability of Bragg-gratings written in tin-doped silica fibres and demonstrate a significant advantage over gratings written in conventional photosensitive fibres.
