Abstract

High-purity Ge-As-Se and Ge-As-S chalcogenide glasses were prepared by modified physical and chemical purification techniques. Using the purified glasses, step-index fibers with a small core (âˆ¼5.5 Î¼m) and large numerical aperture (âˆ¼1.3) were fabricated. When a 13.5-cm-long fiber was pumped with 320 fs pulses at a repetition rate of 10.5 MHz at 4.1 Î¼m, supercontinuum spanning from âˆ¼1.8 to âˆ¼9.8 Î¼m with a dynamic range of Â±10 dB and an average power of âˆ¼3 mW was generated.
