| Abstract: | Coupled higher-order nonlinear Schrdinger equations (CHNLS),governing the evolution of two orthogonal polarization components of ultrashort optical pulse in birefringent fiber,are derived from the dispersion relation.In addition,a class of optical solitary wave solutions,such as the bright-bright,dark-dark,and bright-dark,especially the interesting W-shaped solitary wave solutions for CHNLS equations are found under certain parametric conditions.Furthermore,the properties of these optical solitary solutions are presented. |
