Abstract
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.
