Abstract: We investigate the dynamics of quiescent Bragg solitons in a dual-core fiber Bragg grating system with a phase shift between the gratings where one core has cubic-quintic nonlinearity, and the other is a linear core. Since cubic-quintic nonlinearity is present in one core, our system demonstrates the existence of two distinct and disjoint families of quiescent Bragg solitons within the specified bandgap, classified as Type 1 and Type 2 solitons. Both types of quiescent solitons have been analyzed numerically to assess their stability. The stability analysis reveals that the presence of the phase mismatch between Bragg gratings enhances the overall stability for Type 1 solitons and leads to the formation of stable Type 2 solitons.
