Abstract :
In this letter, we report on the first experimental demonstration of a time-division multiplexed frequency-swept Raman pump used to adaptively flatten the gain of a Raman amplifier. By means of a single, but tunable Raman pump laser operating in the C-band, an ON-OFF Raman gain flatness of 0.6 dB over 15 nm (or 1.5 dB over 30 nm) at an average ON-OFF Raman gain of 22 dB could be achieved for a pump wavelength range of 22 nm.
