摘要

Two types of multipole solitons—specifically, dipole and tripole solitons—are obtained in the fractional second-third order nonlinear Schrödinger system with a parity-time symmetric potential. Their existence and stability under the influence of fractional order effects within this PT-symmetric potential are systematically investigated. Furthermore, the transmission stability of these dipole and tripole solitons is evaluated through direct numerical simulations.
