Query: Bright-dark vector soliton solutions for the coupled complex short pulse
  equations in nonlinear optics   Under investigation in this paper are the coupled complex short pulse
equations, which describe the propagation of ultra-short optical pulses in
cubic nonlinear media.Through the Hirota method, bright-dark one- and
two-soliton solutions are obtained. Interactions between two bright or two dark
solitons are verified to be elastic through the asymptotic analysis. With
different parameter conditions of the vector bright-dark two solitons, the
oblique interactions, bound states of solitons and parallel solitons are
analyzed.
