Propagation of Spatial Soliton in a Parity-Time Symmetric Index Profile

We report the behavior of special soliton propagating along the axis of a parity time symmetric (PTS) waveguide, whose real part is a secant-hyperbolic profile.Numerical results show that the swing behavior depends on the amplitude of soliton, its initial input position, and the maximum amplitude of the imaginary part of the PTSprofile.
