Glass and optical fibers doped with nanoparticles for Photonics

Glass, in its most general sense, is a non-crystalline solid with a glass transition [AF 3 601]. The non-crystalline aspect refers to the long-scale disordered appearance of the glassy lattice. For example, in the case of silica glass (SiO₂), the lattice is made up of SiO₄ tetrahedra linked together by oxygen atoms (with the silicon atom at the center of the tetrahedron), but the arrangement of the tetrahedra is not periodic as in the case of a crystal (such...
