Description
Summary:We report the fabrication of tellurite composite microstructured optical fibers (CMOFs) which consist of a TeO 2 --Li 2 O--WO 3 --MoO 3 --Nb 2 O 5 (TLWMN) tellurite glass core and TeO 2 --ZnO--Na 2 O--La 2 O 3 (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).
