掺杂As2S8波导的Optical Stopping效应

he optical stopping effect in no-doping, low concentration of Tin- and Phosphorus-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 Tin-doped sample can significantly improve the ms degree response in the fast-recovery process, and has the effect in decreasing the residual propagation loss. But in Phosphorus-doped sample, effects are contrary to Tin-doped sample. Based on the experimental results, some analysis and discussions are presented.
