摘要：

We consider dynamical stability of quiescent gap solitons in coupled Bragg gratings with dispersive reflectivity in a cubic-quintic nonlinear medium. It is found that there exist two disjoint families of quiescent solitons within the bandgap, namely Type 1 and Type 2 solitons. Also, in each family, there exist symmetric and asymmetric solitons. It is found that dispersive reflectivity has a stabilizing effect on asymmetric solitons. In addition, the symmetric Type 2 solitons are always unstable.
