Retardation data captured by polarimetric stress-measurements in optical fibers have been reinterpreted in terms of both stress and inelastic strain. The linear dependence of strain birefringence on fiber drawing tension defines the Kohlrausch-Williams-Wat ...
The sol-gel technology offers highly interesting prospects for fiber fabrication. The main advantage is the possibility to incorporate any dopants and co-dopants soluble in a suitable solvent. Generally, these dopants are homogeneously dissolved in the mat ...

Graded-Index (GRIN) lenses with a diameter of 125 μm are presented. This diameter enables the assembly of the GRIN lenses onto an optical micro-system using the same passive alignment grooves as used for the light carrying optical fibers. In contrast to re ...
In this paper, we study a coherent optical MIMO (COMIEMO) multi-mode fiber link proposed for enhancing the fiber information capacity. We examine the statistical characterization of the equivalent MIMO channel and the improvement in the fiber capacity due ...
Sub-ppm hydrogen chloride (HCl) and water vapour (H2O) monitoring using photoacoustic spectroscopy in optical fibre manufacturing is reported. The development and performance of a sensor based on an acoustic resonant configuration is described, and on-site ...
An optical fiber sensor is designed to simultaneously measure strain and temperature in an adaptive composite material. The sensor is formed by splicing two fiber Bragg gratings (FBGs) close to each other, which are written in optical fibers with different ...
Stimulated Brillouin scattering makes possible the generation of synthesized gain spectra, so that innovative slow light schemes can be realized, ranging from broadband tunable delays to a zero-gain situation identical to an ideal electromagnetically-induc ...
Optical fibers have crucially contributed to promote the concept of distributed sensing with a large impact. The different types of fiber optics distributed sensing techniques are reviewed and their performances and limits are presented. ...
In this thesis, we describe a method for the numerical reconstruction of the complete wavefront properties from a single digital hologram: the amplitude, the phase and the polarization state. For this purpose, we present the principle of digital holographi ...
