Abstract :
A high-finesse extrinsic fibre Fabry-Perot cavity with a longitudinal dimension of several micrometres is interrogated using a broadband source, and the spectral shift of a specific resonance band is employed to implement strain and temperature sensors with resolutions of 0.015 με and 0.001°C, respectively
