Abstract
The letter investigates the dispersion of GeO2 glass core and F-doped GeO2 glass cladding single-mode optical fibre. It is estimated that the total dispersion goes to zero at about λ = 1.77 μm. The material dispersions of these glasses are also measured. Material dispersion of GeO2 glass, which contains fluorine of 0.41 wt%, vanished at λ = 1.722μm. This occurs at λ = 1.734 μm for pure GeO2 glass.Keywords
