报告了As_2S_8非晶态薄膜波导的光学截止（optical-stopping）效应的实验过程、初步结果和机理分析.介绍了硫系非晶态As2S8薄膜波导的制备工艺,以及实验光路和光学截止现象的过程.在实验基础上,结合有关硫系非晶态半导体中的其他一些光诱起现象的报道,我们提出了以微结构变动为前提、结合半导体能级理论的电子泵浦模型,解释了实验现象.
The experimental, preliminary results and mechanism analysis of the optical-stopping effect of As_2S_8 amorphous thin film waveguides were reported.The preparation process of sulfur-based amorphous As2S8 thin film waveguides and the experimental optical path and optical cut-off process Based on the experiments and the reports of some other light induced phenomena in chalcogenide amorphous semiconductors, we propose an electronic pumping model based on the change of microstructure and the theory of semiconductor energy levels, and explain the experimental phenomena .
