Book excerpt: L'essor des amplificateurs optiques à fibre dopée erbium dans les années 1980 a exploité la transition 4I13/2 [in] 4I15/2 et a permis la transmission et l'amplification de signaux sur la bande C (1530-1560 nm) sans avoir recours aux coûteuses conversions optique/électrique. Les amplificateurs optiques présentent plusieurs avantages par rapport aux amplificateurs électriques, y compris la capacité de produire du gain à plusieurs longueurs d'ondes différentes simultanément. Cependant, comme la capacité de transmission de la fenêtre actuellement exploitée (1,55[mu]m) est saturée même après utilisation des techniques de multiplexage dense en longueur d'ondes (DWDM), il est nécessaire d'ouvrir des fenêtres à des longueurs d'ondes autre que 1,55 [mu]m. Ainsi, les amplificateurs à fibre dopée Tm - dans des matrices fluorées possèdent une nouvelle fenêtre d'émission à 1,48 [mu]m, ont montré un vif succès grâce à leur énergie de phonon plus basse par rapport à celle de la silice. Les verres de sulfure montrent une énergie de phonon encore plus basse que les verres fluorures. Par conséquent, les verres de sulfure dopés Tm3+ sont un candidat potentiel pour la réalisation des amplificateurs à fibre optique. Les propriétés physiques générales d'une stabilité thermique excellente dans les verres de sulfure sont présentées. La relaxation multiphonon, considérée comme le processus le plus important dans les transitions non-radiatives entre les niveaux énergétiques des rare-terres a été soigneusement discuté. Les propriétés spectroscopiques des verres de chalcogénure dopés Tm3+, basées sur le comportement de leur transition à 1,48 [mu]m sont également présentées. Les niveaux d'énergie, les sections efficaces de transition, la forme de la bande de gain, les durées de vie calculées et mesurées ont été analysés dans cette thèse. Une analyse fondamentale basée sur les études de spectroscopie du Thulium peut nous aider à mieux reconnaître les problèmes qui ont conduit jusqu'à présent au manque de succès des verres de sulfure dopés avec des ions terre-rare. Un phénomène décrivant le processus de relaxation rapide entre la matrice hôte et les ions dopants a été découvert et a été confirmé par les expériences. Ce modèle a ouvert des possibilités pour la réalisation pratique du pompage dans les amplificateurs à base de fibre de chalcogénure.

Book excerpt: The unique properties and functionalities of chalcogenide glasses make them promising materials for photonic applications. Chalcogenide glasses are transparent from the visible to the near infrared region and can be moulded into lenses or drawn into fibres. They have useful commercial applications as components for lenses for infrared cameras, and chalcogenide glass fibres and optical components are used in waveguides for use with lasers, for optical switching, chemical and temperature sensing and phase change memories. Chalcogenide glasses comprehensively reviews the latest technological advances in this field and the industrial applications of the technology.Part one outlines the preparation methods and properties of chalcogenide glasses, including the thermal properties, structure, and optical properties, before going on to discuss mean coordination and topological constraints in chalcogenide network glasses, and the photo-induced phenomena in chalcogenide glasses. This section also covers the ionic conductivity and physical aging of chalcogenide glasses, deposition techniques for chalcogenide thin films, and transparent chalcogenide glass-ceramics. Part two explores the applications of chalcogenide glasses. Topics discussed include rare-earth-doped chalcogenide glass for lasers and amplifiers, the applications of chalcogenide glasses for infrared sensing, microstructured optical fibres for infrared applications, and chalcogenide glass waveguide devices for all-optical signal processing. This section also discusses the control of light on the nanoscale with chalcogenide thin films, chalcogenide glass resists for lithography, and chalcogenide for phase change optical and electrical memories. The book concludes with an overview of chalcogenide glasses as electrolytes for batteries.Chalcogenide glasses comprehensively reviews the latest technological advances and applications of chalcogenide glasses, and is an essential text for academics, materials scientists and electrical engineers working in the photonics and optoelectronics industry. - Outlines preparation methods and properties, and explores applications of chalcogenide glasses. - Covers the ionic conductivity and physical aging of chalcogenide glasses, deposition techniques for chalcogenide thin films, and transparent chalcogenide glass-ceramics - Discusses the control of light on the nanoscale with chalcogenide thin films, chalcogenide glass resists for lithography, and chalcogenide for phase change optical and electrical memories

Book excerpt: A comprehensive and up-to-date encyclopedia to the fabrication, nature, properties, uses, and history of glass The Encyclopedia of Glass Science, Technology, History, and Culture has been designed to satisfy the needs and curiosity of a broad audience interested in the most varied aspects of material that is as old as the universe. As described in over 100 chapters and illustrated with 1100 figures, the practical importance of glass has increased over the ages since it was first man-made four millennia ago. The old-age glass vessels and window and stained glass now coexist with new high-tech products that include for example optical fibers, thin films, metallic, bioactive and hybrid organic-inorganic glasses, amorphous ices or all-solid-state batteries. In the form of scholarly introductions, the Encyclopedia chapters have been written by 151 noted experts working in 23 countries. They present at a consistent level and in a self-consistent manner these industrial, technological, scientific, historical and cultural aspects. Addressing the most recent fundamental advances in glass science and technology, as well as rapidly developing topics such as extra-terrestrial or biogenic glasses, this important guide: Begins with industrial glassmaking Turns to glass structure and to physical, transport and chemical properties Deals with interactions with light, inorganic glass families and organically related glasses Considers a variety of environmental and energy issues And concludes with a long section on the history of glass as a material from Prehistory to modern glass science The Encyclopedia of Glass Science, Technology, History, and Culture has been written not only for glass scientists and engineers in academia and industry, but also for material scientists as well as for art and industry historians. It represents a must-have, comprehensive guide to the myriad aspects this truly outstanding state of matter.
