Abstract
The invention is concerned with a structured optical fibre sensor, comprising a light source (), a detection system () and a Bragg grating optical fibre () connected to said source and said system. The light source is a wavelength-tunable laser emission device () comprising a cavity (CA) delimited by a first and a second Sagnac mirror (M, M). The cavity comprises an amplifying medium (AM) and a tunable spectral filter using the Vernier effect (F), said filter (F) comprising at least three resonant rings (R, R, R, R) arranged in cascade, each resonant ring integrating a wavelength-tunable reflectivity loop mirror (MBR).
