Mechanism of optical stopping effect of arsenicsulfide amorphous waveguide

In this paper, the optical stopping effect of thin film waveguide with doping As2S8 and As2S8 is studied. Based on this, the mechanisms of formation and transfer of abnormal electron configuration are discussed, and the dynamic models of optical stopping and reversion process are proposed. The numerical analysis results are in good agreement with the experimental data, so the phenomenon in experiment can be predicted by this model, which implies that this model holds the basic features and the essence of the optical stopping effect.
