Abstract

Using high-intensity (up to 500 GW/cm²) 264 nm laser radiation, we fabricated long-period fibre gratings (LPFGs) in standard telecom and photosensitive fibres and compared the inscription efficiency with that for other existing methods of recording. We studied the temperature sensing properties of the fabricated gratings and demonstrated the effect of thermal recovery of a LPFG resonance peak.
