  bibo_abstract:
  - 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 (P T)-symmetric system of linearly coupled nonlinear Schrödinger
    equations, which describes a Kerr-nonlinear optical coupler with mutually balanced
    gain and loss in its cores. Besides the linear coupling, the overlapping cores
    are coupled through the cross-phase-modulation term too. While the rogue waves,
    built according to the pattern of the Peregrine soliton, are (quite naturally)
    unstable, we demonstrate that the focusing cross-phase-modulation interaction
    results in their partial stabilization. For P T-symmetric and antisymmetric bright
    solitons, the stability region is found too, in an exact analytical form, and
    verified by means of direct simulations@eng
