Studies on Methods of Polarization Controlling Chaos in Dual-ring Er-doped Fiber Lasers
双环掺铒光纤激光器混沌偏振控制方法研究

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.
