Locally pressed fibre Bragg grating pressure sensor [PDF]
, 2006 A spectral-hole created by locally pressing a fibre Bragg grating exhibited a wavelength-shift within the FBG bandwidth. A sensitivity of 74.3pm/(N/mm) was obtained for pressure applied along the slow axis of a high birefringence ...

Regularization for the inversion of fibre Bragg grating spectra [PDF]
Inverse Problems in Science and Engineering, 2021 Fibre Bragg Gratings have become widespread measurement devices in engineering and other fields of application. In all but a few cases, the relation between cause and effect is simplified to a proportional model. However, at its mathematical core lies a nonlinear inverse problem which appears not to have received much attention in the literature.

Fibre Bragg gratings and their applications [PDF]
11th International Conference on Integrated Optics and Optical Fibre Communications. 23rd European Conference on Optical Communications IOOC-ECOC97, 1997 Summary form only given. Optical fibre Bragg gratings are the most significant new fibre device since the EDFA and will have a major impact on the design and implementation of future optical networks. Applications include single and multichannel add/drop filters, EDFA gain stabilising and spectrum flattening filters, dispersion compensation, as well as
