We report the manufacturing and characterization of Tellurite micro structured fibres (MOFs)
with low OH content. The different purification processes used during the fabrication of the
TeO 2-ZnO-Na 2 O glass allowed us to reduce the hydroxyl compounds concentration down
to 1ppm mass. A suspended core MOF was drawn from this material and then pumped by
nanojoule-level femtosecond pulses at 1.7 μm, its zero dispersion wavelength (ZDW), and
well above it at 2.5 μm. We show the related supercontinuum (SC) generated in the two …

We report the manufacturing and characterization of Tellurite micro structured fibres (MOFs) with low OH content. The different purification processes used during the fabrication of the TeO2 - ZnO - Na2O glass allowed us to reduce the hydroxyl compounds concentration down to 1ppm mass. A suspended core MOF was drawn from this material and then pumped by nanojoule-level femtosecond pulses at 1.7μm, its zero dispersion wavelength (ZDW), and well above it at 2.5μm. We show the related supercontinuum (SC) generated in the two distinct dispersion regimes of the waveguide. Moreover, the SC spanning was extended in both visible and mid-IR regions (between 600nm up to 3300nm) by the taperisation of the previously tested MOFs.
