Fluoride glasses : synthesis and properties

Abstract

The discovery of heavy metal fluoride glasses has opened new prospects for fiber optics operating beyond 2 µm with expected losses less than 10(-2) dB/Km. The main interest of fluoride glasses lies in their infrared transmission up to 8 µm in the bulk form and 4.5 µm for optical fibers. We have reported here the preparation, the glass forming systems and properties of heavy metal fluoride glasses
