Rare-earth doped glass-ceramics for photonics applications

Development of the novel waveguides lasers and broadband sources require advanced active materials like rare-earth-doped (RED) glass-ceramics. It offers a combination of the properties of glass (i.e., good mechanical, chemical, and thermal resistance) with the superior luminescence of the crystalline phase derived from their low phonon energy and the ability to incorporate lanthanide ions. The approach of the fabrication and structural-luminescence properties of the RED glass-ceramic in the low-phonon systems based on the TeO₂ and GeO₂ will be presented. The perspectives in manufacturing the Eu³⁺ and Er³⁺ doped glass-ceramic waveguides will be outlined
