Scattering of bright soliton by PJ-symmetric potential well and barrier is investigated numerically. The numerical results show that increasing strength of real part of PJ-symmetric potential can cause repeated reflection, transmission, and trapping regions due to energy exchange between the kinetic energy of incoming soliton and the internal modes of the potential structure. In addition, the width of the scattering windows increases with increase of the imaginary part of the PJ-symmetric potential. The results obtained can be exploited in the development of interferometry as well as for diodes devices in information technology. (C) 2014 Optical Society of America
