Abstract: Fibre Bragg gratings (FBGs) are novel components of communication and sensors. The technique commonly employed for production of FBGs involves exposure of photosensitive germanosilicate fibre cores to intense excimer laser radiation through an optical phase mask located in close proximity of the fibre. FBGs were written using this technique in two different fibre samples and their strain and temperature sensing characteristics were investigated. The paper describes the techniques used for fabrication and their characteristic studies.
