本文报道在tR>>τ(tR为反馈系统延迟时间,τ为液晶的弛豫时间)条件下,液晶混合光学双稳装置中,随着系统参数的改变,自脉冲经倍周期分叉发展到混沌的过程。计算了分叉图,通过频谱和相空间图能清晰地分析系统的动态行为。实验结果与Ikeda理论进行了比较。This paper reports the process of bifureation to chaos of the self-pulsing output with the changing of the parameters of the system in a liquid crystal hybrid optical bistable device under the condition of tR>>τ (where tR is the delay time of the feedback system, τ is the relaxation time of the liquid crystal). The bifurcations and chaos are calculated. The dynamical behavior of the system is analysed by the Fast Fourier Transform and the phase portrait. The experimental result is compared with Ikeda's theory.
