Abstract

We study control-chaos of a dual-ring erbium-doped fiber laser using an anti-parameter pair modulation. And we study this control-chaos method via the inverse modulation of the gain parameters of two key physical parameters of the dualring erbium-doped fiber laser. In terms of physical mechanism, the optical effects of alternating excitation or alternating attenuation of two gain parameters of the laser are found. The control of chaos laser and its new nonlinear dynamic changes are derived. In the control mechanism, the double-parameter reverse modulation pair is found where the laser behavior is very sensitive to the anti-parameter pair modulation because this reverse action modulation combines with induction control dynamic changes. The laser can be controlled to a single-periodic state, a double-periodic state, a threeperiodic state, a four-periodic state, a five-periodic state, a six-periodic state, a seven-periodic state and other highperiodic states. Double-dynamics, frequency controlled-locking and semi-frequency controlled-locking regions are found. The laser exhibits a very imaginative dynamic behavior that has never been seen before, which has important reference value for the study of chaos dynamics, laser technology and control technology.
