Formation Of Extrinsic Scatterers In Zrf4-Based Fluoride Optical Fibres

Formation of extrinsic ZrO light scatterers in ZrF4-based fluroide optical fibres is investigated with respect to resultant oxides in raw materials. Thermodynamic consideration of reaction equilibrium between ZrF4 and oxides possibly included in raw materials, indicates that all oxides concerned can convert ZrF4 to ZrO2. Using low oxide content materials for glass preparation, scatters significantly decrease. In addition, dissolved oxides produced by OH evacuation enhance oxide segregation to form or to grow ZrO2 scatterers during melting process.
