Distribution and Intensity of the Built-in Field in Poled Silica Thermally Based on a Junction Model

Abstract:

Formation of depletion region and the charge distribution are analyzed using multi-charges’ migration under a polling field in fused silica. The internal fields induced are calculated based on a junction model. The field distributions and their intensities within the whole depletion inside the silica are calculated. The maximum field is on the order of 109 V/m in a abrupt junction, and the optical nonlinearities generated by this internal field are consistent with the experimental results published, which proves the junction model is reasonable and feasible to calculate optical nonlinearity in air by thermal polling.
