Paper Abstract

In this work, two all-fibre interferometric configurations based on suspended core fibres (SCF) are investigated. A Fabry-Pérot cavity made of SCF spliced in-between segments of single-mode and hollow-core fiber is proposed. An alternative sensing head configuration formed by the insertion of a length of SCF as a birefringence element in a Sagnac interferometer is also demonstrated. The sensitivity to pressure and temperature was determined for both configurations.
