Figure 2. (a) The phase transition regions of nonlinear modes for SNLSE (5) as the function of the initial amplitude A and width w when taking C = 0. (b) The phase transition curves of rogue wave for SNLSE (5) as the function of the initial amplitude A and width w when taking C = 1. Here, σ1 = −4.8 and −9.6. (a1)–(a6) The evolution results of the initial incident pulse (8), correspond to the black points 1–6 in figure 2(a). Here, A = 1.2, ω = 4, 3.7, 2.5, 1.6, 1.1, and 0.5, respectively. FWHM of (a1)–(a6) are W = 1.02, 1.10, 1.17, 1.33, 1.64, and 0.86, respectively. (b1)–(b2) The evolution results of the initial incident pulse (8), correspond to the black points 1 and 2 in figure 2(b), respectively. Here, A = 1.2, ω = 1.4 and 0.5. FWHM of (b1)–(b2) is W = 1.25 and 2.58.
