Figure 1: Gain (Solid curve) and NF (dotted curve) spectra of the FOPA made with 1 km DSF and pumped at 1537.6 nm with 1.5 W power. The zero-dispersion wavelength is 1537 nm, and the dispersion slope is 0.034 ps n m − 2 k m − 1 . The nonlinear coupling coefficient is 1.8  W − 1 k m − 1 . Maximum value of Raman-gain coefficient for DSF is 0.8  W − 1 k m − 1 , at the temperature of 300 K.
