摘要

We consider the Maxwell-Bloch equations that describe the propagation of coherent optical pulses in a resonant two-level medium associated with the self-induced transparency phenomenon. Using degenerate Darboux transformation, the dynamical evolution of coherent multi-optical rogue waves is constructed with different kinds of wave patterns: fundamental-, triangular-, and ring-type patterns. We also discuss the explicit analytical forms of these universal patterns as well as we provide the corresponding numerical data of the obtained optical rogue waves.
