A theoretical model of a dual-ring-dual-ring driving-response chaotic synchronous system with dual-ring single-mode erbium-doped fiber lasers is presented. One dual-ring single-mode erbium-doped fiber laser is used as a driving subsystem and the other with two additional feedback paths is used as a response subsystem. Two phase-shift-controllers control the reverse of the phase shift of the injection lights and together with the feedback paths of the response subsystem realize the control of two reverse-phase-shift of the lights. Based on the reverse-phase and feedback method, chaotic synchronization can be controlled by adjusting the injection light phase-shifts with the help of the phase-shift-controllers. Numerical simulations show that by this method chaotic synchronization can be achieved effectively no matter whether or not the coupling driving control of the injection lights is symmetrical.
