  In this paper, ultra-broad band optical signal amplification are analyzed and
demonstrated by utilizing supercontinuum generation propagating over the
photonic crystal fiber. The coupled nonlinear Schroodinger equation containing
parametric process and stimulated Raman scattering effect was analyzed and
solved to calculate the variation of signal gain with frequency. The dependence
of the gain spectra on nonlinear and chromatic dispersion coefficients as well
as the geometrical parameters of photonic crystal fiber are discussed. The
results show that when using a pump at wavelength 1450nm and peak power 1600W,
the gain spectra covers from 1300 to 1700nm with the peak gain 100dB. This
amplification mechanism have potential in full-wave optical fiber
communication.
