【摘要】 本文研究了手性介质构成的光纤中光孤子的传输问题。基于麦克斯韦方程和手性介质中的极化关系,首先得到了描述手性光纤中两圆偏振成分耦合的非线性薛定谔方程,并且使用分步傅立叶方法对孤子的传输演化进行了数值模拟, 分别研究了在弱耦合情况和强耦合情况下,对应的幅度相等的两圆偏振孤子成分在演化过程中的相互作用,并讨论了两幅度不相等的偏振成分所产生的准孤子性质,最后展示了手性光纤中孤子成分束缚在光信息同步传输方面的优点。更多还原

【Abstract】 In this paper, the optical soliton transmission issue in the fiber consisting of a chiral medium is studied. At first, based on Maxwell equations and polarization relation of chiral medium, coupled nonlinear Schr? dinger equations, which is describing the coupling between two circularly polarized components, are obtained. Numerical simulation is carried out for the transmission of solitary components by using split step Fourier method. Corresponding to the weak and strong coupling cases, the interaction between two balanced circularly polarized solitary components in transmission is investigated. At the same time, the quasi-soliton properties of unbalanced polarized components are discussed, Finally, the advantage of soliton component banding in chiral fiber for the synchronous transmission of optical information is presented.更多还原
