摘要: Abstract Some analytical solutions of a (1+1)-dimensional nonlinear Schrodinger equation with inhomogeneous diffraction and nonlinearity in the presence parity-time symmetric potential are derived. All characteristic parameters such as amplitudes, speeds widths adapted both to variations. The dynamical behaviors two kinds nonautonomous solitons different potentials investigated respectively exponential decreasing waveguide periodic modulated system. Moreover, phase changes for illustrated detail. These results may provide alternative methods applications synthetic systems.
