Instabilities, solitons and rogue waves in PT-coupled nonlinear waveguides
Bludov, Yuliy V.; Driben, R.; Konotop, Vladimir V.; Malomed, B. A.We considered the modulational instability of continuous-wave backgrounds, and the related generation and evolution of deterministic rogue waves in the recently introduced parity–time (PT )-symmetric system of linearly coupled nonlinear Schr¨ odinger equations, which describes a Kerr-nonlinear optical coupler with mutually balanced gain and loss in its cores. Besides the linear coupling, the overlapping cores a...
