Journal ArticleDOI
Relative humidity sensor with optical fiber Bragg gratings
TL;DR: Tests in a controlled environment indicate that the novel concept for an intrinsic relative humidity (RH) sensor that uses polyimide-recoated fiber Bragg gratings has a linear, reversible, and accurate response behavior.
Journal ArticleDOI
Bragg grating fast tunable filter for wavelength division multiplexing
A. Iocco,Hans G. Limberger,René Paul Salathé,L.A. Everall,K.E. Chisholm,John A.R. Williams,Ian Bennion +6 more
TL;DR: In this paper, a Bragg grating fast tunable filter prototype working over a linear tuning range of 45 nm with a maximum tuning speed of 21 nm/ms has been realized.
Journal ArticleDOI
Polarization microscopy by use of digital holography: application to optical- fiber birefringence measurements
Tristan Colomb,F. Dürr,Etienne Cuche,Pierre Marquet,Hans G. Limberger,Rene-Paul Salathe,Christian Depeursinge +6 more
TL;DR: A digital holographic microscope that permits one to image polarization state and the birefringence induced by internal stress in an optical fiber is measured and compared to a standard method, which had been developed to obtain high-resolution bireFringence profiles of optical fibers.
Journal ArticleDOI
Embedded optical fiber Bragg grating sensor in a nonuniform strain field: Measurements and simulations
TL;DR: In this paper, the use of embedded optical fiber Bragg gratings to measure strain near a stress concentration within a solid structure was investigated, and it was shown that the form of the spectra in transmission varies between gages that are at different distances from the notch tip under given loading conditions.
Journal ArticleDOI
Compaction- and photoelastic-induced index changes in fiber Bragg gratings
TL;DR: In this paper, the tension on the core of singlemode fibers is strongly increased by the formation of a Bragg grating and this tension increase lowers the refractive index because of the photoelastic effect.
