【摘要】实验研究了未掺杂和低浓度掺锡和掺磷的As2S8薄膜波导的光阻断效应,提供了三种样品的光阻断响应曲线、室温退激实验数据和光谱测试数据.结果表明,掺锡样品可以明显提升毫秒级响应的快过程恢复作用,同时还具有减少残留传输损耗的效果,掺磷的效果则相反.结合实验结果给出了分析讨论.更多还原

【Abstract】 The optical stopping effect in undopeel and low concentration Sn-and P-doped As2S8 amorphous thin films is studied experimentally. The optical stopping response curve, experimental data of room temperature deexcitation and spectral testing data of the samples are provided. The results show that, the Sn-doped sample can significantly improve the ms range response in the fast-recovery process, and has the effect in decreasing the residual propagation loss. But in P-doped sample, the effects are contrary to that in the Sn-doped sample. Based on the experimental results, some analysis and discussions are presented.更多还原
