摘要: We numerically study the effect of additive gaussian white noise in dynamics a timedelayed feedback system. The system is semiconductor laser witb optical from distant reflector. For moderate levels presents several coexisting attractors, and above threshold value induce jumps among these attractors. Based on residence times probability density, P(I), we show that with increasing attractor jumping exhibits resonant behavior. P(I) peaks at multiples external-cavity delay time, strength reaches maximum for an optimal level noise. results are explained by interplay delayed feedback.
