Controlling optical spatiotemporal chaos of coupled phase-conjugate map system with nonlinear feedback
非线性反馈法控制相位共轭波的光学时空混沌

The optical phase-conjugate resonator consists of one normal mirror and one phase-conjugate mirror made of an instantaneous response lossless Kerr medium.Using the nonlinear feedback,we control the temporal chaos in the phase-conjugate resonator and spatiotemporal chaos in the coupled phase-conjugate map system.Stable control has been realized.The simulation shows that this controlling technique can be implemented easily in practical systems just by adjusting the feedback strength.The in-advance knowledge of the dynamic system is not required.The results are useful to theoretical analysis of chaos in phase-conjugate resonators.
