Abstract:   (1750 Views)
In this paper we derive analytical dark soliton solutions in a nonlinear PT-symmetric coupler with gain in one waveguide and loss in the other in normal dispersion regime by using perturbation method. The usual solutions of noncoupled equations are dark solitons. Evaluating perturbation analytically shows that perturbations which guaranty the stability are in two forms of bright and dark solitons. However, in systems with the usual solutions of bright solitons, only a bright soliton perturbation satisfies the stability.
