Abstract :
A chalcogenide-tellurite hybrid microstructured optical fiber is designed and fabricated by the rod-in-tube drawing technique. The core is made of chalcogenide glass with a composition of 15Ge-3Ga-12Sb-70S (atm%, GGSS) and the cladding is made of tellurite glass with a composition of 78TeO2-5ZnO-12Li2O-5Bi2O3 (mol%, TZLB). The loss is ~1.1 dB/m at ~2.0 μm. Zero dispersion wavelength of the HMOF is shifted down to ~2370 nm from GGSS material dispersion ~4600 nm. Supercontinuum (SC) generation is investigated by pumping a 1-cm-long HMOF with the wavelengths of ~2000, 2300, and 2600 nm from a tunable optical parametric amplifier system. Flattened and broadband SC generation from ~950 to 3350 nm with the intensity flatness of 6 dB bandwidth is obtained with the peak power of ~40 MW at the wavelength of ~2300 nm.
