Transmission of Multipole Solitons in Parity-Time Symmetric Scarff Potentials
The existence and stability of dipole and tripole solitons in Parity-Time(PT) symmetric Scarff complex potentials are investigated, including linear case, and self-focusing and self-defocusing nonlinear cases. For linear case, the PT-breaking points, eigenvalues and multipole linear modes for different modulated depths of PT symmetry Scarff complex potential are obtained numerically. For nonlinear cases, the existence and stability of multipole solitons are studied in self-focusing and self-defocusing media. For a fixed modulated depth, the eigenvalue for multipole linear modes is equalt to the critical propagation constant bc of multipole solitons existence. Multipole solitons are stable with the propagation constants close to bc both for self-focusing and self-defocusing nonlinearities.
