文摘：We report on octave-spanning supercontinuum generation under pumping with 1360 nm, 120fs pulses, in an all-solid, all-normal dispersion photonic crystal fiber. The fiber was drawn from thermally matched oxide soft glasses with a hexagonal lattice 35μm in diameter, 2.5μm solid core and pitch of ∧/d = 0.9. The fiber was designed for normal dispersion broadly flattened in the 1200-2800 nm range. Experimentally recorded supercontinuum spectrum covered a 900-1900 nm bandwidth and was reconstructed with good agreement using numerical modeling. To the best of our knowledge, this is the first report of an experimentally demonstrated octave-spanning supercontinuum bandwidth, reaching as far as 1900nm in the all-normal dispersion regime.
