摘要: Abstract We investigate the optical properties with two-dimensional (2D) Scarff parity–time (PT) symmetric potentials, including linear case, and self-focusing self-defocussing nonlinear cases. For PT-breaking points, eigenvalues eigenfunction for different modulated depths of 2D PT symmetry complex potential are obtained numerically. The points increase linearly increasing real part potential. Below modes real, however, above points. cases, existence fundamental multipole solitons is studied in media. eigenvalue case equal to critical propagation constant b c soliton existing.
