Abstract

We study the sensitivity of light dynamics to the internal phase of propagating pulses in the two types of PT-symmetric models. The first is a waveguide array with an embedded pair of waveguides with gain and loss, called PT-coupler, and the second is a planar coupler which models a chain of PT-symmetric couplers. For the first model we investigate the soliton scattering on the mode localized on the coupler, while for second model we study the collision of two breathers. For both models we find that the light dynamics is sensitive to the internal phases of the interacting pulses. Particularly, the PT-symmetry breaking can take place or not, depending on the internal phases of two signals having identical other parameters.
