Long-wavelength continuum generation about the second dispersion zero of a tapered fiber

Author(s): Harbold, JM; Ilday, FO; Wise, FW; Birks, TA; Wadsworth, WJ; Chen, Z | Abstract: A dispersion zero near 1300 nm of a narrow-diameter tapered fiber is used to generate broadband, near-infrared light. When femtosecond pulses at 1260 nm with 750 pJ of energy are launched in proximity to the second zero-dispersion wavelength, a continuum spanning 1000-1700 nm is produced.
