A sketched demonstration of the density plot in the limit \ | ν | ( a 1 2 + a 2 2 ) in Akhmediev breather solution using Eq. (6) with C1 = −1, C2 = 1, C3 = 3, C4 = −3, a1 = 0.8, and a2 = 0.7. Note that there is one peak and two caves in each periodic. (a)–(c) Density plots for component |q1|2, and (d)–(f) density plots for component |q2|2. The modulation parameter ν of the Akhmediev breather is as follows: (a) and (d) ν = 0.7746; (b) and (e) ν = 1; (c) and (f) ν = 1.063.
