(INVITED)Infrared luminescence of chalcogenide glasses doped with rare earth ions and their potential applications
Abstract
This article deals with sulfur and selenium-based glasses doped with rare earth ions. It reviews the most significant glass compositions and their related thermal and mechanical properties, with emphasis given to optical and spectroscopic properties in the infrared domain. Optical transparency, multiphonon relaxations, luminescence in optical fibers and planar waveguides doped with trivalent rare earth ions are presented in details. Applications as new compact light sources and lasers, especially for the mid-IR domain, are shown.
