Multiple-Pulse Operation and Bound States of Solitons in Passive Mode-Locked Fiber Lasers

Figure 14

Steady-state distances between two solitons interacting through a lumped saturable absorber. The white circle corresponds to the first soliton. The black squares and grey circles do to the steady-state second soliton with the phase differences 𝜋 and 0, respectively. 𝑎=0.5, 𝐷_𝑟=0.01, 𝐷_𝑖=0.1, 𝑞=1.5, 𝑝=1, 𝑠_𝑛𝑙=1.
