Abstract

We have demonstrated a continuum spectrum generation utilizing adiabatic compression in Raman amplifier. Continuum medium consists of only dispersion-shifted fiber as a counter-pumped Raman gain medium. The power uniformity of the continuum spectrum can be improved by adjusting wavelength and power of the Raman pump source. A 16-nm-wide uniform continuum spectrum with the power fluctuation less than 3 dB is generated from an 18.0 ps pulse-width seed pulse produced by an electroabsorption modulator.
