Abstract :
We investigate the synthesis of flat parametric response of a dual-pumped device with a distant pump separation ranging from 130 to 180 nm. The Raman contribution to the nonlinear polarization introduced predictable gain ripple and dispersion fluctuation along the highly nonlinear fiber had to be precisely accounted for. A 3-dB equalized gain was observed over 100 nm using 130-nm separated pumps. Record gain bandwidth of 155 nm was also measured for the first time.
