Controlling chaos in Er-doped fiber laser

摘要

In this paper, we present a scheme of controlling chaos in an Er-doped fiber dual-ring laser with one polarized mode by using the linear feedback method. Numerical results shown that under some stiffness of feedback the controlled system has negative maximum Laypunov exponents (MLE) and separate spectra, which demonstrate that controlling the chaotic system into the stable states could be realized by adjusting the feedback stiffness.
