【Abstract】 A new method of VCSELs for controlling chaos is studied,which is based on the parameter switching modulation.The chaos the system is controlled to its fixed point and nP periodic orbits by using the spontaneous emission factor.proves the validity and robustness of this proposed control method.It is shown that high-order harmonic distortion is minimized with large spontaneous emission factor.The quantitative relation among the stability,multi-period or the position of the bifurcation and the parameter switching are given using the bifurcation diagram,the temporal waveforms and the phase space portrait.更多还原
