Semirational rogue waves of the three coupled higher-order nonlinear Schrödinger equations

Abstract

Under investigation in this paper is the three coupled Hirota equations in the long distance communication or ultrafast signal routing system. Semirational solutions are derived by virtue of the Darboux dressing transformation. Based on the discussion of the parameters in solutions, we see that the semirational rogue waves are formed by the interaction between the rogue wave and the dark–dark–bright/breather soliton.
