摘要
用向量场的观点系统地研究吸收型光学双稳态方程的时变分岔问题及其动力学行为 ,探讨分岔转迁滞后现象中的内在规律性 .当入射光场是常量时 ,用新方法分析了光学双稳态的存在性和临界慢化现象 ;当入射光场分别随时间线性慢变或周期慢变时 ,通过量级平衡给出分岔转迁的不同量级关系 ;当入射光场的振幅或频率随时间线性慢变时 ,研究了双稳时变系统的分岔和动力学行为 ,并揭示新的奇怪吸引子的出现 .
Time\|dependent bifurcation and dynamical behaviors of the absorptive optical bistability equation are investigated systematically from the point of view of vector field.Internal relations for delayed bifurcation transitions are discussed.When the input optic field is constant,the existence of optical bistability and the phenomenon of critical slowing down are analyzed through a new way.When the input optic field is varied slowly with time linearly or periodically,different scaling relations are given by scaling balances.When the amplitude or frequency of the input optic field is varied slowly and linearly with time,the bifurcation and dynamical behaviors for the time\|dependent system of bistability are also studied .A new strange atractor is revealed..
