Abstract
The glass formation and compositional dependences of glass thermal properties and optical properties were investigated in TeO2–ZnO–Na2O–P2O5 system. The refractive index at 1.55μm and glass transition temperature varied in a wide range from 1.513 to 2.036 and from 265°C to 376°C by controlling of the TeO2/P2O5 and ZnO/Na2O content, respectively. These properties enable phospho-tellurite glasses with large freedom in designing and fabrication of hybrid microstructured optical fiber. The structures of glasses were investigated by Raman spectra to understand their dependence of structure on composition. Using the present glasses, some hybrid microstructured optical fibers with various dispersion profiles were designed.
