(color online) Spectrum evolutions along the fiber for the multiple FWM. (a) Cascaded dispersion-decreased fibers with 10-m-long large- fiber and 10-m-long, small- fiber successively, (b) cascaded dispersion-increased fibers with 10-m-long small- fiber and 10-m-long large- fiber successively, (c) 20-m-long large- fiber, (d) 20-m-long small- fiber. Large = 0.075 (ps/nm²)/km, small = 0.00075 (ps/nm²)/km. Color bar shows the spectral power in unit dBm.
