摘要
实验研究了纯As2S8以及掺杂As2S8非晶态薄膜波导光阻断效应的回复过程。分析了各样品内部的化学键结构,利用轨道杂化理论和电子能带理论,提出了光阻断效应回复过程的动力学方程,通过数值分析与实验结果的对比,得出该模型能够很好地解释光阻断效应的回复机理,揭示了实验的本质。
In this research, the recovery process of optical stopping effect in thin film waveguide with doping As2S8 and As2S8 is studied. Based on this, the chemical bond structures of the samples are analyzed. With the help of the theory of hybridize valence orbital and the theory of electron energy band gap, the dynamical equation of recovery process is proposed. The numerical analysis results are well matched with the experimental data, and the recovery process of optical stopping effect can be predicted by the deduction of the model. It reveals the basic nature of the experiment.
