Abstract
We show that nonlinear optical structures involving a balanced gain-loss profile can act as optical diodes. This is made possible by exploiting the interplay between the fundamental symmetries of parity (P) and time (T), with optical nonlinear Kerr effects. This unidirectional propagation is demonstrated for the case of a PT -symmetric nonlinear coupler and a PT-symmetric Bragg grating.
