ABSTRACT
Spatial distribution of electric field after electron beam irradiation of MgO-doped LiNbO3 with resist layer on irradiated polar surface has been studied by computer simulation. The space distribution of electrons was simulated by Casino software and analyzed by original algorithm to construct analytical function. The distribution of electric field was evaluated by Comsol software. The correlation between the value of polar component of electric field on the resist – MgOLN interface and quality of the domain patterns has been demonstrated. The calculated optimal electron energy for given resist layer thickness allowed to create fine periodical domain structure for nonlinear optical application.
