The one-pump optical fiber parametric amplification (FOPA) has been well known to be a means for realizing wideband amplification when the group-delay dispersion (β2) is small at the pump wavelength. In this paper, we report one-pump FOPA in short Bismuth-Oxide-based highly nonlinear fiber (Bi-HNLF) that has large normal dispersion at 1550nm, both theoretically and experimentally, for the first time to the best of our knowledge. We found that, due to the large β4 along with large β2, FOPA in the Bi-HNLF is very narrowband, and its gain peak wavelength is tunable in proportional to the pump wavelength. We achieved the gain bandwidth as narrow as 0.75nm and gain peak as high as 58dB in the experiment using a 2m-long Bi-HNLF.
