Abstract This paper mainly studied the influence of the feedback strength on the dynamics of nonlinear optical feedback systems. We adopt Delay Partial Differential Equations as the theoretical model of nonlinear optical feedback systems, through the method of theoretical analysis and numerical simulation to study dynamics of the systems under the change of the feedback strength. We find that the system has a wide range of dynamical behavious as the feedback strength is increased gradually. It experiences periodic states, chaotic breather with slow and fast time scales, and then fully developed chaos.
