Breathers in PT-symmetric optical couplers
I. V. Barashenkov, Sergey V. Suchkov, Andrey A. Sukhorukov +2
We show that the parity-time (PT) symmetric coupled optical waveguides with gain and loss support localised oscillatory structures similar to the breathers of the classical m…

Wave scattering on a domain wall in a chain of PT-symmetric couplers
Sergey V. Suchkov, Sergey V. Dmitriev, Boris A. Malomed +1
We study wave propagation in linear arrays composed of pairs of conjugate waveguides with balanced gain and loss, i.e. arrays of the PT-symmetric couplers, where the linear spectru…
