• We report the fabrication of tellurite composite microstructured optical fibers (CMOFs) which consist of a TeO₂--Li₂O--WO₃--MoO₃--Nb₂O₅ (TLWMN) tellurite glass core and TeO₂--ZnO--Na₂O--La₂O₃ (TZNL) tellurite glass cladding. Flattened chromatic dispersion and tunable zero dispersion wavelength (ZDW) were realized in the small core diameter (${\sim}1.5$ μm) fiber with six surrounding air holes. The optical loss was measured to be about 4.0 dB/m in the spectral range of 1510--1640 nm. Supercontinuum (SC) generation was demonstrated by a femtosecond laser pumping at 1.55 μm. The threshold pump power for this novel tellurite CMOF was the lowest among tellurite microstructured optical fibers (MOFs).
