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.

Cutting-edge techniques for yielding high-quality chalcogenide glasses This pioneering work describes the technology, developed over a 50-year period, to utilize chalcogenide glasses as infrared optical materials. Methods for qualitatively identifying chalcogenide glass compositions and producing high-purity homogeneous glass are discussed. Chalcogenide Glasses for Infrared Optics includes unique production techniques developed through the author's work at both Texas Instruments (TI) and Amorphous Materials, Inc. (AMI). The production of vacuum float zoned silicon, gallium arsenide, and cadmium telluride, all useful in infrared technology, is explained. The book highlights examples of how glass composition can be changed to enhance a particular property. Coverage includes: Transmission of light by solids Physical properties of chalcogenide glasses Glass production Careful characterization of glass properties Conventional lens fabrication--spherical surfaces Molding of unconventional aspheric lenses with diffractive surfaces Glass processes for other applications IR imaging bundles made from chalcogenide glass fibers Production of infrared crystalline materials at AMI Development of an automatic ellipsometer system at TI

Chalcogenide glass is made up of many elements from the Chalcogenide group. The glass is transparent to infrared light and is useful as a semiconductor in many electronic devices. For example, chalcogenide glass fibers are a component of devices used to perform laser surgery. The properties of chalcogenide glass result not only from their chemical composition and atomic structure, but also from the impact of numerous external factors. A comprehensive survey is presented of the properties of chalcogenide glass under various external impacts. Practical recommendations are presented for a wide range of applications. Part II is the second part of a three-volume work within the Semiconductors and Semimetals series. * The first collective monograph written by Eastern European scientists on the electrical and optical properties of chalcogenide vitreous semiconductors (CVS). * Contributions by B.G.

Photonics, whichusesphotonsforinformationandimageprocessing, islabeled as one of the technologies of the 21st century, for which nonlinear op- cal processes provide the key functions of frequency conversion and optical switching. Chalcogenide glasses are based on the chalcogen elements S, Se, and Te. These glasses are formed by the addition of other elements such as Ge, As, Sb, Ga, etc. These glasses are low-phonon energy materials and are generally transparentfromthevisibletoinfrared.Chalcogenideglassescanbedopedby rare-earth elements such as Er, Nd, Pr, etc., and hence numerous applications ofactiveopticaldeviceshavebeenproposed.Theseglassesareopticallyhighly nonlinear and could therefore be useful for all-optical switching. This book is a review of recent progress in the science and technology of chalcogenide glasses, with an emphasis on their nonlinear optical properties, forgraduatestudents, practisingengineersandscientistsfromawidemultid- ciplinary area such as physics, chemistry, electrical engineering and material science. Since the interest in this area is growing worldwide, a book dealing with this subject will be of great value to researchers of varied backgrounds. Chalcogenide glasses and their electronic, structural, and photoinduced properties are introduced. Techniques to characterize the linear and nonlinear optical properties of these glasses are introduced and used to measure the optical constants of chalcogenide glasses in the form of bulk, thin ?lm and ?ber. The possibilities of fabricating passive and active devices are present
