Abstract

In this research, the recovery process of the optical stopping effect on an amorphous arsenic sulfide thin-film waveguide is studied, both on the net As2S8 and doping As2S8 waveguide. Based on the experimental results, we analyzed the chemical bond structure of the samples. The hybrid orbital theory and electron energy bandgap theory are applied in order to establish the model of optical stopping and the recovery process. The numerical analysis results are well matched with the experiment data, which indicates that the model properly explains the optical stopping effect phenomenon. The model also can be applied to predict the recovery process of the optical stopping effect.
