چکیده مقاله
In this paper, we study the higher order nonlinear Schrdinger HNLS equations for a directional ber optic coupler with the third order dispersion TOD , self steeping SS and stimulated Raman scattering SRS effects and gainin one waveguide and loss in the other We have reduced the system equations toan uncoupled HNLS equation which has bright and dark soliton solutions It isshown that the Hamiltonian for this equation has a PT Symmetric form Furthermore the equilibrium points are found and the discussion about theirstability is presented
