• Using the multiple-carrier model, the process of thermal/electric-field poling in fused silica is analyzed in this study for the first time. The depletion region may be composed of a positively charged layer, an ionosphere layer and a negative depletion layer, and the charge density distribution in the depletion region is derived and obtained. The calculation results show that the distribution of the charge density in the entire depletion region has a quasi-step profile, and both the positively charged region and the negative depletion layer have an approximately uniform distribution. Expressions for the depletion width and the electric field distribution in the depletion region are obtained. Theoretical results show that the peak electric field is located in the interior of the depletion region, and the internal electric field is about $10^{9}$ V/m, up to two orders of magnitude higher than the applied initial poling field.
