Nonlinear dynamics in photonic systems with Parity-Time symmetry

Kivshar, Yuri


We review our recent progress in the study of nonlinear photonic systems with balanced gain and loss described by the models with parity-time (PT) symmetry. We discuss the nonlinear dynamics in optical waveguide couplers and show that for intensities below a threshold, the field oscillates between the waveguides, whereas above the threshold the symmetry breaking is observed. This nonlinearity-induced effect can be generalized to other systems, as well as can be observed experimentally. We then...[Show more]
