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 PTS profile.
