- Abstract
Dark solitons are widely applied in optical fiber communication system due to the characteristics of strong anti-interference and slow attenuation. The coupled nonlinear Schrödinger equations with the higher-order effects of third-order dispersion, self-steepening and self-frequency shift, which is modeled the propagation of ultrashort optical pulse through a multimode fiber or birefringence fiber, have been investigated analytically. By using the Hirota method, exact dark solitons, anti-dark solitons and dark double-hump solitons are constructed. The transmission characteristics of those solitons are analyzed, and the conditions for the transformation of states between them are discussed. Those presented results provide a new idea for the transformation of dark soliton states.
