Superregular breathers and state transitions in a resonant erbium-doped fiber system with higher-order effects

We present the superregular breather solutions that are nonlinear superposition of a pair of travelling breathers propagating in opposite directions. We further study the full- and half-transition modes of the superregular breather solution, which appears as a result of the coupled and higher-order effects. These waves reduce to small localized perturbations of the background at time zero.
