双环掺铒光纤激光器混沌偏振控制方法研究

提出双环掺铒光纤激光器激光混沌的偏振耦合控制以及部分偏振控制方法,偏振耦合控制能控制耦合相互作用以控制激光混沌,部分偏振控制是控制部分偏振耦合效应以控制激光混沌.数值模拟了偏振耦合控制混沌和某一个环的部分偏振控制混沌,它们都能实现把双环掺铒光纤激光器激光混沌控制到稳定态和周期态上;通过实时调控光的偏振方向,这两种混沌控制方法都能实时地、动态地、有效地控制激光混沌进入到稳定态和周期态上.

Studies on Methods of Polarization Controlling Chaos in Dual-ring Er-doped Fiber Lasers

Methods of chaos controlled with coupling polarization and fractional polarization are presented. The coupling polarization controlling can control the coupling interaction to control chaotic lasing, and the fractional polarization controlling can control the fractional coupling polarization effect to control chaotic lasing. Numerically simulations illustrate that chaos laser can be controlled into stable states and periodic states by parallel adjusting the direction of the two coupling polarization, or adjusting the direction of the fractional polarization of a ring in dual ring erbium doped fiber. The methods can be real time dynamically effectively control chaotic lasing into stable states and periodic states by adjusting real time optical polarization angle.
