Abstract

Fibre sensitivity to the temperature, longitudinal strain or pressure, is a very important fibre feature in many applications, such as sensing application or telecommunication. The most common way to modify (either mitigate or strengthen, depending on application) this sensitivity is to change the material properties by doping or to employ microstructured fibres. In some cases the precise adjustment of a doping level and sophisticated design of air-hole arrangement is needed to obtain required features of a fibre, for example to increase sensitivity to the hydrostatic pressure and avoid cross-sensitivity to the temperature [1].
