Bright-dark solitary wave pairs resulting from stimulated Raman scattering and loss.
We show that under the combined effects of stimulated Raman scattering and loss, the pump and Stokes waves can form a bright-dark solitary wave pair. Our analysis takes into account dispersive and walk-off effects as well as the processes of self-phase modulation and cross-phase modulation. The physical origin of this formation is discussed.
