Thermal poling and space charge dynamics with surface ...

Thermal poling of fused silica produces a space charge region with a high electric field that results in an induced second-order nonlinearity. Cooling with the voltage applied leaves a frozen-in electric field, primarily concentrated near the anode region. We present experimental results along with a model for the charge dynamics of the poling process that includes ionization and charge ...
