amplifier in the 1 µm band with a record bandwidth of more than 20 THz and a peak gain of
almost 40 dB. This is achieved by using a photonic crystal fiber with a high figure of merit
and strongly reduced longitudinal dispersion fluctuations. Due to their unique bandwidth
and gain characteristics, fiber parametric amplifiers at 1 µm provide an interesting alternative
to solid-state or ytterbium-doped fiber amplifiers for ultrafast optical pulse and signal …
