Radiation Effects on Silica-Based Optical Fibers: Recent Advances and Future Challenges
Sylvain Girard,Jochen Kuhnhenn,Andrei Gusarov,Benoit Brichard,M. Van Uffelen,Youcef Ouerdane,Aziz Boukenter,Claude Marcandella +7 more
TL;DR: In this article, the effects of radiation on silica-based optical fibers are discussed and the main results regarding the fiber vulnerability and hardening to radiative constraints associated with several facilities such as Megajoule class lasers, ITER, LHC, nuclear power plants or with space applications.

Quartz as a natural luminescence dosimeter
Frank Preusser,M.L. Chithambo,Thomas Götte,Marco Martini,Marco Martini,Karl Ramseyer,Emmanuel J. Sendezera,George J. Susino,Ann G. Wintle,Ann G. Wintle +9 more
TL;DR: Luminescence from quartz is commonly used in retrospective dosimetry, in particular for the dating of archaeological materials and sediments from the Quaternary period as discussed by the authors, which is related to the interaction of natural radiation with mineral grains, by the activation of and subsequent trapping of electrons at defects within the quartz lattice.
Journal ArticleDOI
Fibre gratings and devices for sensors and lasers
TL;DR: In this paper, the authors present a whole host of processes which can enhance and tailor the properties of both conventional and not-so-conventional fibre Bragg gratings, including multi-photon excitation of germanosilicate based defects with CW 244 nm light.

Defect energy levels in density functional calculations: alignment and band gap problem.
TL;DR: This study describes how calculated defect levels shift when the band gap approaches the experimental value, showing average shifts of at most 0.2 eV irrespective of band gap.

Photosensitivity in optical fiber waveguides: Application to reflection filter fabrication
TL;DR: In this paper, the observation of photosensitivity in Ge-doped core optical fibers is reported. The photosensitivity is manifested by light-induced refractive index changes in the core of the waveguide.

High pressure H/sub 2/ loading as a technique for achieving ultrahigh UV photosensitivity and thermal sensitivity in GeO/sub 2/ doped optical fibres
TL;DR: In this article, high pressure "hydrogen loading" has been used to sensitise standard singlemode fibres, resulting in the largest reported UV induced index changes for low GeO/sub 2/ fibres.
