Abstract :
The physical model of single-ring feedback phase-shift controlling and the model of dual-ring feedback phase-shift controlling are proposed in this text according to the method of chaos feedback phase-shift for dual-ring erbium-doped fiber laser. On this basis, the output of system was simulated by computer. After synthetically analyzing the simulating result, we reached a conclusion that it´s effective to control the output into chaos state, stable state or periodic state. By comparison, we knew the feedback coefficient and feedback phase-shift have a different impact on different models.
